DNS SEEDERS HEALTH

Updated: Fri Feb 27 21:37:47 2026 UTC

This page reports 7-day network statistics for Bitcoin DNS seeders. Bitcoin nodes join the Bitcoin peer-to-peer network by initially making outgoing connections to peers announced by these seeders via A (IPv4) and AAAA (IPv6) DNS records, so it is important that they maintain high availability to allow new Bitcoin nodes to bootstrap reliably. The list of DNS seeders used in the reference implementation is available from GitHub.

TERMINOLOGY

IPv4 RTT	90th percentile round-trip time (in milliseconds) to fetch A record containing a list of IPv4 peers from the DNS seeder.
IPv6 RTT	90th percentile round-trip time (in milliseconds) to fetch AAAA record containing a list of IPv6 peers from the DNS seeder.
TTL	90th percentile duration (in seconds) during which A record from the DNS seeder remain unchanged.
Service prefixes	Hex prefix, e.g. x1, placed at the start of DNS seeder's hostname, e.g. x1.seed.bitnodes.io, to tell the seeder which service bits a peer must support to be included in the A/AAAA record.
