DNS Coffee ☕
Records

IPs

Look up an IPv4 or IPv6 address to see every nameserver that has ever resolved to it, and when. CIDR notation (e.g. 205.251.192.0/18) lists every stored IP in the subnet. These addresses come from glue records in the zone files we import, not from DNS lookups.

Addresses Seen in Glue Over Time
Distinct addresses active in glue records on each date, plotted as a weekly average of the daily counts.
First-Ever Addresses per Day (last 90 days)
Addresses seen in glue for the first time anywhere, per day, from the daily change feeds. An address counts once, on the day it first appeared — not again when another zone's glue starts pointing at it. These feeds began on 2026-07-25, so the series starts there.
Most Used Addresses
