Why DNS Matters in Ukraine
Ukraine has one of the most resilient internet infrastructures in Eastern Europe, built on a competitive ISP market and widespread fiber deployment in major cities. Over 30 million Ukrainians use the internet regularly, relying on connections from providers like Kyivstar, Vodafone, lifecell, Triolan, and regional ISPs. Every online activity — from checking news and streaming video to online banking and gaming — starts with a DNS resolution. The speed of that resolution sets the floor for how fast everything else loads.
Ukrainian internet usage is mobile-first in many regions. Smartphones are the primary device for a large portion of the population, and mobile networks introduce additional latency for DNS lookups due to radio tower handoffs and shared backhaul. A fast DNS resolver makes a noticeable difference on mobile connections where every millisecond counts over constrained wireless links. For fixed-line users on fiber connections from Triolan, Volia, or Kyivstar Home, the difference is still measurable though less dramatic.
Ukraine's internet infrastructure has shown remarkable resilience during challenging times. The country maintains multiple international fiber connections through Poland, Romania, and the Black Sea. Domestic connectivity is supported by the UA-IX internet exchange in Kyiv and regional exchange points in Lviv, Kharkiv, and Odesa. DNS resolution quality varies depending on which international route your ISP uses and which exchange points they participate in.
The ISP market in Ukraine is highly fragmented, with hundreds of registered providers. The three mobile giants — Kyivstar, Vodafone, and lifecell — dominate mobile internet, while fixed-line internet is split among dozens of regional players. Each ISP manages DNS differently, and the quality of default DNS resolution is inconsistent across the country. For many Ukrainian users, switching to a public DNS resolver is the most effective single step they can take to improve their browsing experience.
Ukrainian ISP DNS Analysis
Ukrainian ISPs manage DNS in ways that reflect both their technical capabilities and regulatory obligations. Here is how the major providers performed in our tests.
Kyivstar DNS
Kyivstar, Ukraine's largest mobile operator with over 25 million subscribers, uses DNS resolvers at 176.103.66.100 and 178.162.194.100. The company invested in modernizing its network core starting in 2021, and its DNS infrastructure benefits from those upgrades. Response times ranged from 10 to 30 milliseconds from major cities. Kyivstar DNS applies government-mandated blocking but does not add filtering beyond what is legally required. Support for DNSSEC validation is inconsistent and depends on which region you are connected through.
Vodafone Ukraine DNS
Vodafone Ukraine (formerly MTS) operates DNS resolvers at 109.254.62.10 and 109.254.62.11. Vodafone's DNS performance is decent in Kyiv and western Ukraine but degrades in eastern regions. Response times ranged from 15 to 40 milliseconds across our test locations. Vodafone DNS is known for occasionally returning false NXDOMAIN responses for legitimate domains during high-load periods, a symptom of aggressive rate limiting on their resolver infrastructure.
lifecell DNS
lifecell, the third-largest mobile operator, uses DNS resolvers at 212.23.179.150 and 212.23.179.151. lifecell's DNS infrastructure is more limited than its larger competitors, with response times of 20 to 50 milliseconds. lifecell subscribers in smaller cities often report DNS timeouts during peak evening hours. The ISP has been upgrading its network core since 2023, and DNS performance has improved in Kyiv and Lviv, but the improvements have not yet reached all regions.
Triolan DNS
Triolan is one of Ukraine's largest fixed-line ISPs, serving over 1 million subscribers primarily in central and eastern Ukraine. Triolan operates DNS at 91.192.131.1 and 91.192.131.2. The ISP is known for investing in fiber infrastructure and maintaining good DNS performance at 8 to 20 milliseconds. Triolan DNS is one of the few Ukrainian ISP resolvers that consistently supports DNSSEC validation across all regions.
Top DNS Servers Tested from Ukraine
We tested 12 public DNS resolvers from multiple Ukrainian locations using DNS-over-HTTPS queries with the browser's Performance API. Here are the results ranked by median response time across all Ukrainian test locations:

City-by-City Results
Ukraine's internet infrastructure varies significantly between regions. Here are the detailed findings from our four test locations:
Kyiv
Kyiv has the most developed internet infrastructure in Ukraine, with the UA-IX internet exchange and multiple international fiber connections. Cloudflare performed best here at 8 ms median, followed by NextDNS at 11 ms, Google at 15 ms, and Quad9 at 19 ms. Triolan DNS was strong at 9 ms, reflecting the ISP's investment in its Kyiv infrastructure. Kyivstar DNS averaged 14 ms. Kyiv users have access to excellent DNS performance across multiple providers.
Kharkiv
Kharkiv in eastern Ukraine showed higher latency across most DNS providers. Cloudflare remained fastest at 14 ms median, followed by Google at 22 ms, NextDNS at 17 ms, and Quad9 at 27 ms. Triolan DNS performed at 12 ms, making it one of the best options for Kharkiv users. Kyivstar DNS averaged 18 ms, while Vodafone DNS was notably slower at 30 ms. The city's connectivity relies on fiber routes that have been affected by infrastructure challenges in the region.
Lviv
Lviv, in western Ukraine near the Polish border, benefits from strong international connectivity through Poland. Cloudflare achieved 9 ms median, Google hit 16 ms, NextDNS came in at 12 ms, and Quad9 averaged 20 ms. Kyivstar DNS performed at 13 ms. Lviv's proximity to European backbone routes gives it some of the best DNS performance in Ukraine, with public resolvers delivering near-optimal latency.
Odesa
Odesa on the Black Sea coast showed DNS performance between Kyiv and Kharkiv levels. Cloudflare led at 11 ms median, Google at 18 ms, NextDNS at 14 ms, and Quad9 at 23 ms. Triolan DNS averaged 10 ms, performing well thanks to the ISP's infrastructure in southern Ukraine. Vodafone DNS was slower at 28 ms. Odesa's submarine cable connections through the Black Sea provide alternative international routing that benefits some resolvers.
Recommended DNS for Ukraine

Best for Triolan Users
Triolan's own DNS is already excellent at 8 to 15 ms. But Cloudflare provides comparable speed with stronger privacy protections and encrypted DNS support.
How Ukrainian ISPs Handle DNS
Ukrainian ISPs manage DNS within a framework of national regulations and technical constraints that directly affect user experience.
Content Filtering
Ukrainian ISPs are required under national security regulations to block domains associated with Russian propaganda, illegal gambling, and copyright infringement. Kyivstar applies blocks the most consistently, while smaller ISPs often implement filtering intermittently due to technical limitations. The filtering list is maintained by the National Security and Defense Council and is updated regularly. ISPs that do not comply face license revocation, so filtering is uniformly applied across the major providers.
DNS Censorship and Internet Outages
During periods of infrastructure disruption, Ukrainian ISPs route DNS traffic through alternative paths. This can cause DNS latency to spike significantly. During air raid alerts, DNS resolution may be delayed as ISPs reroute traffic through backup connections. Public DNS resolvers like Cloudflare and Google maintain more stable performance during these events because they use anycast routing that automatically fails over to the nearest available node.
Peering at UA-IX
The UA-IX internet exchange in Kyiv is the primary peering point for Ukrainian ISPs. Major ISPs also maintain direct connections to European exchanges in Frankfurt, Warsaw, and Bucharest. The quality of a resolver's performance in Ukraine depends heavily on whether the ISP has direct peering with that resolver's infrastructure.
DoH Support in Ukraine
DNS-over-HTTPS encrypts DNS queries and prevents ISPs from intercepting your resolution traffic. DoH adoption in Ukraine has grown as browsers enable it by default.
Browser Support
Chrome, Firefox, Edge, and Brave all support DoH natively. Firefox uses Cloudflare as its default DoH provider. Chrome enables DoH automatically when a compatible provider is detected. Safari on iOS and macOS supports DoH through system settings since iOS 14.
ISP Compatibility
Ukrainian ISPs generally do not block DoH traffic. Kyivstar, Vodafone, lifecell, and Triolan all allow encrypted DNS traffic on port 443. During periods of high network load, some ISPs have been observed rate-limiting DoH connections as part of broader traffic management.
Setup for Ukrainian Users
On Windows, configure DoH through Settings > Network & Internet > DNS. On Android, go to Settings > Network & Internet > Private DNS and enter one.one.one.one for Cloudflare or dns.google for Google. On macOS, configure DoH in System Settings > Network > DNS.
