DNS Landscape in Ireland
Ireland benefits from excellent internet infrastructure as a major European tech hub. Dublin hosts the INEX (Internet Neutral Exchange) and is a landing point for numerous transatlantic subsea cables connecting North America to Europe. Most major public DNS resolvers have well-distributed points of presence in Dublin, providing strong performance for both European and US-hosted content.
Cloudflare DNS (1.1.1.1) averages 10 ms in Dublin and 14 ms in Cork. Google DNS (8.8.8.8) averages 12 ms in Dublin and 16 ms in Cork. Quad9 averages 11 ms in Dublin and 15 ms in Cork. Ireland's position as a gateway between North America and Europe provides excellent peering diversity.
Performance Rankings
Cloudflare 1.1.1.1 is the fastest option for most Irish users, averaging 10-14 ms across major cities. Google 8.8.8.8 is competitive at 12-16 ms. Quad9 performs well at 11-15 ms. NextDNS averages 13 ms. OpenDNS averages 16-20 ms. Ireland's strong international connectivity ensures all major providers deliver excellent performance.
ISP DNS in Ireland
Ireland's major ISPs include Eir, Vodafone Ireland, and Three Ireland. Eir DNS averages 8-14 ms. Vodafone DNS averages 10-16 ms. Three DNS averages 12-18 ms. Irish ISP DNS is generally good, but switching to Cloudflare can still improve resolution times by 10-20%, especially for international domains.
