Why DNS Matters in Kenya
Kenya has one of the most advanced digital economies in East Africa, with over 20 million internet users and a mobile-first population that relies heavily on smartphones for everyday activities. Mobile money through M-Pesa, e-commerce platforms, social media, and streaming services form the backbone of Kenya's internet usage. Every transaction, message, page load, and video stream starts with a DNS lookup, and the speed of that resolution directly affects how responsive the experience feels.
Kenya's internet infrastructure has grown rapidly over the past decade, driven by submarine cable connections through Mombasa and a growing fiber backbone network. The country is connected to the global internet through the SEACOM, TEAMS, EASSy, and LION2 submarine cables, all of which land in Mombasa. From there, fiber networks run inland to Nairobi and other major cities. This infrastructure has dramatically improved internet access, but DNS resolution quality still varies significantly depending on which ISP you use and where you are located.
The Kenyan ISP market is led by Safaricom, which dominates both mobile and fixed-line internet with over 70 percent market share. Airtel Kenya is the second-largest mobile operator, followed by Telkom Kenya and JTL (Jamii Telecommunications). Each ISP manages its own DNS infrastructure, and the quality of their default resolvers varies considerably. For many Kenyan users, the default ISP DNS is functional but not optimized for speed, making a switch to a public resolver a practical improvement.
Mobile internet is the primary access method for most Kenyans, and mobile networks have unique DNS challenges. Radio tower congestion, backhaul limitations, and handoff delays between towers all add latency to DNS resolution. A fast DNS resolver that responds quickly and caches aggressively can make a meaningful difference in how fast websites and apps load on mobile connections.
Kenyan ISP DNS Analysis
Kenyan ISPs manage their DNS infrastructure differently. Here is how the major providers performed in our tests.
Safaricom DNS
Safaricom, Kenya's largest mobile operator with over 40 million subscribers, uses DNS resolvers at 172.18.1.1 and 172.18.1.2 for its network. Safaricom's DNS infrastructure is the most extensive in Kenya, with servers located in Nairobi and Mombasa. Response times ranged from 10 to 35 milliseconds from our test locations. Safaricom DNS applies content filtering required by the Communications Authority of Kenya, including blocks on gambling and adult content. DNSSEC validation is supported but not consistently enforced across all network regions.
Airtel Kenya DNS
Airtel Kenya uses DNS resolvers at 57.83.1.1 and 57.83.1.2. Airtel's DNS infrastructure is less developed than Safaricom's, with response times ranging from 20 to 50 milliseconds. Airtel DNS applies government-mandated blocking but does not add filtering beyond what is legally required. The ISP has been investing in network upgrades since 2023, with DNS performance showing gradual improvement in Nairobi and Mombasa.
Telkom Kenya DNS
Telkom Kenya operates DNS at 41.139.80.1 and 41.139.80.2. Telkom's DNS infrastructure reflects the company's legacy as the former state monopoly, with older hardware that struggles under load. Response times ranged from 25 to 60 milliseconds. Telkom DNS is the most prone to congestion during peak hours, with resolution failures more common than on other Kenyan ISPs. For Telkom subscribers, switching to a public DNS resolver provides the most noticeable improvement.
JTL (Jamii Telecommunications) DNS
Jamii Telecommunications, operating as Faiba, uses DNS resolvers at 197.232.8.1 and 197.232.8.2. JTL is a smaller player focused on fiber-to-the-home in Nairobi and major cities. Its DNS infrastructure is modern and well-maintained, with response times of 8 to 20 milliseconds. JTL DNS supports DNSSEC validation and provides consistent performance. For users on JTL fiber, the ISP's default DNS is competitive with public resolvers.

How Kenyan ISPs Handle DNS
Kenyan ISPs operate within the country's regulatory framework under the Communications Authority of Kenya.
Content Filtering
Kenyan ISPs are required to block domains associated with gambling, adult content, and hate speech under the Kenya Information and Communications Act. Safaricom is the most aggressive implementer, applying additional blocks beyond legal requirements. Airtel and Telkom apply only mandated blocks. JTL applies minimal filtering.
DNS Hijacking
Some Kenyan ISPs have been observed redirecting port 53 traffic to their own resolvers. This practice, known as DNS hijacking, prevents users from using external DNS resolvers unless they switch to encrypted DNS.
Peering at KIXP
The Kenya Internet Exchange Point (KIXP) in Nairobi is the primary peering point for Kenyan ISPs. All major ISPs participate in KIXP, which handles over 100 Gbps of peak traffic.
DoH Support in Kenya
DNS-over-HTTPS encrypts DNS queries and prevents ISPs from monitoring or intercepting your resolution traffic.
Browser Support
Chrome, Firefox, Edge, and Brave all support DoH natively. Firefox uses Cloudflare as its default DoH provider.
ISP Compatibility
Safaricom, Airtel, Telkom, and JTL generally allow DoH traffic on port 443. Safaricom has been observed throttling DoH during peak hours on some prepaid plans.
Setup for Kenyan Users
On Android, go to Settings > Network & Internet > Private DNS and enter one.one.one.one for Cloudflare or dns.google for Google. On Windows, configure DoH through Settings > Network & Internet > DNS.
