Enter a domain above to check DNS propagation across resolvers.
Copy these into a terminal to check the major providers directly (commands update as you type a domain above):
ISP resolvers cache heavily for millions of customers, so they're the usual reason a change takes a day or two to appear. They only answer their own customers, so they can't be queried from this site — run the command from a device on that network to check one:
194.168.4.100 · 194.168.8.100
62.6.40.178 · 62.6.40.179
90.207.238.97 · 90.207.238.101
212.159.6.9 · 212.159.13.49
195.166.130.1 · 195.166.130.2
212.58.224.1
Or check whatever resolver your device uses (no @ needed):
Global resolvers are anycast, so results are consistent worldwide. UK resolvers are open recursive resolvers from public-dns.info, each probed from our server so only reachable ones are listed; a resolver may still occasionally drop a query.
