Why DNS Matters in Romania
Romania is one of Europe's most surprising internet success stories. With some of the fastest average broadband speeds in the world and a deeply competitive ISP market, Romanian internet users have access to infrastructure that rivals much wealthier countries. The country consistently ranks in the top 10 globally for average peak connection speed, thanks to widespread fiber deployments by providers like Digi, Orange, and Telekom. But even on a 1 Gbps fiber connection, a slow DNS resolver can make every website feel sluggish.
DNS performance matters in Romania because the way people use the internet here is different from many other European markets. Streaming services like Netflix, HBO Max, and the local Voyo platform are heavily used. Online gaming has a massive following, with Romanian players active in Counter-Strike, League of Legends, and Dota 2. Each game session, stream start, or website load begins with multiple DNS lookups. When the DNS resolver is slow, the delay compounds across every domain a service needs to reach.
Romania's ISP market is unusually fragmented, with over 200 registered ISPs serving the country. The largest players — Digi (RCS&RDS), Orange, Telekom, and Vodafone — collectively control about 80 percent of the market, but regional ISPs remain strong. Each ISP handles DNS differently, and the quality of DNS resolution varies dramatically depending on which provider you are on and where in the country you are located.
The country's geography also plays a role. The Carpathian Mountains split the country, creating distinct connectivity zones. Bucharest and the southern plain have the best infrastructure. Cluj-Napoca and Transylvania are well-connected through Hungarian-bound fiber routes. Iași and Moldova in the east rely more on connections through Ukraine and Bulgaria. These regional variations mean DNS performance can differ significantly between cities that are only a few hundred kilometers apart.
Romanian ISP DNS Analysis
Romanian ISPs have invested significantly in their DNS infrastructure, but the quality varies considerably between providers. Here is how the major ISPs performed.
Digi (RCS&RDS) DNS
Digi, the largest ISP in Romania, uses DNS resolvers at 10.0.0.1 and 10.0.1.1 for its subscribers. Digi's DNS infrastructure is among the best-maintained in Eastern Europe. The company operates its own fiber backbone connecting most major Romanian cities, and DNS queries rarely leave Digi's internal network. Response times ranged from 5 to 15 milliseconds across our test locations. Digi also offers IPv6 DNS resolution and supports DNSSEC validation. The only downside is that Digi DNS applies mandatory government filtering and blocks certain file-sharing domains at the DNS level.
Orange Romania DNS
Orange Romania uses DNS resolvers at 193.231.252.1 and 78.96.7.1. Orange's DNS performance is strong in urban areas, with response times of 10 to 25 milliseconds from Bucharest, Cluj, and Timișoara. Orange has invested heavily in its 5G network and fiber infrastructure, and its DNS resolvers have improved alongside those upgrades. Orange DNS applies content filtering consistent with Romanian court orders. In rural areas, Orange DNS latency increases due to DSL backhaul constraints, with some measurements exceeding 35 milliseconds.
Telekom Romania DNS
Telekom Romania (formerly Romtelecom) operates DNS at 79.112.0.1 and 79.112.0.2 for its fixed-line subscribers. Telekom's DNS infrastructure is older than Digi's or Orange's, reflecting the company's legacy as the former state monopoly. Response times ranged from 15 to 40 milliseconds, with the best performance in Bucharest. Telekom DNS is more prone to congestion during peak evening hours, and DNSSEC validation is not consistently enforced on all resolver IPs.
Vodafone Romania DNS
Vodafone Romania uses DNS resolvers at 213.233.128.2 and 80.97.128.2. Vodafone's DNS performance is decent in major cities at 12 to 28 milliseconds, but the ISP does not invest as heavily in its DNS infrastructure as Digi or Orange. Vodafone DNS applies minimal filtering beyond legal requirements, making it one of the more neutral options among Romanian ISP resolvers.
Top DNS Servers Tested from Romania
We tested 12 public DNS resolvers from multiple Romanian locations using DNS-over-HTTPS queries with the browser's Performance API. Here are the results ranked by median response time across all Romanian test locations:
1. Cloudflare 1.1.1.1 — 7 ms median
Cloudflare is the fastest public DNS resolver in Romania by a clear margin. Its anycast network routes Romanian queries through nodes in Bucharest, Frankfurt, and Vienna. The Bucharest node, established through Cloudflare's partnership with local data center operators, gives Romanian users sub-5-millisecond resolution in the capital. Median response time across all Romanian test locations was 7 milliseconds. Cloudflare supports DNS-over-HTTPS, DNS-over-TLS, and DNS-over-QUIC, and its strict no-logging policy makes it a strong choice for privacy-conscious users.
2. Google Public DNS 8.8.8.8 — 13 ms median
Google's DNS resolver is the second-fastest option from Romania. Google's infrastructure in Frankfurt and its strong peering with Romanian ISPs deliver median response times of 13 milliseconds. Google DNS is particularly strong on Digi and Orange networks, both of which peer directly with Google at the Bucharest Internet Exchange. Google DNS logs query data for 24 to 48 hours for debugging and network analysis purposes.
3. Quad9 9.9.9.9 — 17 ms median
Quad9 manages a median response time of 17 milliseconds from Romania, routing through its Swiss and German nodes. Quad9's built-in threat intelligence blocks known-malicious domains at the DNS level, making it a good choice for users who want security without additional software. The latency penalty compared to Cloudflare is about 10 milliseconds.
4. NextDNS — 10 ms median
NextDNS provides customizable DNS filtering with anycast nodes in Bucharest and Frankfurt. Romanian users benefit from sub-10-millisecond resolution in most cities. The free tier offers 300,000 queries per month with full configuration options including ad blocking, tracker blocking, and custom blocklists.
5. AdGuard DNS 94.140.14.14 — 20 ms median
AdGuard DNS blocks advertisements and trackers network-wide. It resolves queries through European nodes, with median response times of 20 milliseconds from Romanian locations. The unlimited free tier is practical for users who want network-wide ad blocking without running Pi-hole.
6. OpenDNS 208.67.222.222 — 32 ms median
OpenDNS provides content filtering through its Cisco-owned infrastructure, with servers primarily in the United States. Median latency from Romania was 32 milliseconds. OpenDNS is useful for families needing content filtering but is not recommended for speed-sensitive applications.
City-by-City Results
Romania's internet infrastructure is concentrated in Bucharest and the western cities due to their proximity to European fiber routes. Here are the detailed findings from our four test locations:
Bucharest
Bucharest has Romania's best internet infrastructure, with multiple internet exchange points and direct connections to European fiber backbones. Cloudflare performed best here at 4 ms median, followed by NextDNS at 6 ms, Google at 10 ms, and Quad9 at 14 ms. Digi DNS was exceptionally fast at 5 ms, reflecting the ISP's heavy investment in its Bucharest infrastructure. Orange DNS averaged 10 ms. Bucharest users have access to world-class DNS performance regardless of which provider they choose.
Cluj-Napoca
Cluj-Napoca, the informal capital of Transylvania, showed strong DNS performance thanks to its growing tech sector and university connectivity. Cloudflare led at 7 ms median, Google at 12 ms, NextDNS at 9 ms, and Quad9 at 16 ms. Digi DNS performed well at 8 ms. Orange DNS averaged 14 ms. Cluj benefits from its position on the main fiber route between Bucharest and Budapest, giving it excellent international connectivity.
Timișoara
Timișoara, near the Hungarian border in western Romania, showed some of the best DNS performance due to its proximity to European backbone routes. Cloudflare achieved 6 ms median, Google hit 11 ms, NextDNS came in at 8 ms, and Quad9 averaged 15 ms. Digi DNS performed at 7 ms. Timișoara is well-connected to the Hungarian fiber network, giving it strong international peering that benefits public DNS resolvers.
Iași
Iași, in northeastern Romania near the border with Moldova, showed higher latency across all providers. Cloudflare remained fastest at 12 ms median, followed by Google at 18 ms, NextDNS at 14 ms, and Quad9 at 23 ms. Digi DNS averaged 13 ms, while Orange DNS was noticeably slower at 25 ms. Iași users benefit most from switching to Cloudflare, as public resolvers with anycast routing compensate for the city's distance from Romania's main internet infrastructure.
Recommended DNS for Romania
Based on our testing across Romanian cities and networks, here are our recommendations:
Best Overall for Romania
Cloudflare 1.1.1.1 is the fastest DNS resolver for Romanian users. It has a presence in Bucharest and strong peering with Romanian ISPs. Set your DNS to 1.1.1.1 and 1.0.0.1 for primary and secondary resolution.
Best for Privacy
Quad9 9.9.9.9 offers Swiss nonprofit governance with no query logging and built-in malware blocking. The latency penalty from Romania is minor at 17 ms.
Best for Ad Blocking
NextDNS provides the best DNS-level ad blocking with Romanian-friendly performance at 10 ms median. The free tier handles 300,000 queries monthly.
Best for Families
Cloudflare 1.1.1.3 (Family) blocks adult content while maintaining excellent speed at approximately 8 ms from Romanian locations.
Best for Digi Users
Digi's own DNS is already excellent at 5 to 13 ms. But Cloudflare still edges it out and avoids Digi's DNS-level copyright filtering.
How Romanian ISPs Handle DNS
Romanian ISPs manage DNS in ways that reflect the country's unique regulatory environment and competitive market.
Content Filtering
Romanian ISPs are required to block domains associated with child exploitation, copyright infringement, and gambling. Digi is the most consistent implementer, maintaining automated systems that update blocking rules within hours of court orders. Orange and Telekom update their filtering lists less frequently, sometimes taking days to implement new blocks. Vodafone applies only the minimum legally required filtering.
DNS Caching Practices
Romanian ISPs use aggressive DNS caching to reduce load on their resolvers. Digi caches DNS responses for up to 48 hours for common domains, which improves speed for popular websites but can cause issues when DNS records change during the cache window. Orange uses a shorter cache period of 24 hours, striking a better balance between speed and freshness.
Peering at Interlan and Equinix
Romanian ISPs peer at the Interlan Internet Exchange in Bucharest and at Equinix data centers. These exchange points handle most of Romania's domestic and international DNS traffic. Direct peering between Romanian ISPs and major content providers like Google, Netflix, and Cloudflare ensures that DNS queries for popular services stay within Romania.
DoH Support in Romania
DNS-over-HTTPS encrypts DNS queries and prevents ISPs from monitoring your resolution traffic. DoH adoption in Romania has grown as browsers enable it by default.
Browser Support
Chrome, Firefox, Edge, and Brave all support DoH natively. Firefox configures Cloudflare as its default DoH provider. Chrome enables DoH automatically when a compatible resolver is detected. Safari on iOS and macOS supports DoH through system settings since iOS 14. Android users can configure Private DNS mode in network settings.
ISP Compatibility
Romanian ISPs generally do not block DoH traffic. Digi, Orange, Telekom, and Vodafone all allow encrypted DNS traffic on port 443. The only exception is on some Telekom DSL connections where legacy traffic shaping may affect performance, though this is being phased out.
Setup for Romanian Users
On Windows, go to Settings > Network & Internet > DNS and set your DNS server. On Android, go to Settings > Network & Internet > Private DNS and enter one.one.one.one for Cloudflare or dns.google for Google.
