See Where a Domain Really Points
DNS decides where a website loads from and where its email is delivered. When a site shows the old server after a move, email stops arriving, or a certificate refuses to issue, the answer is almost always in a DNS record. These tools query live DNS so you can see what the rest of the internet sees.
The DNS Lookup returns every common record type in one view. When you need a single type, use the focused lookups: A and AAAA for server addresses, CNAME for aliases, MX for mail servers, TXT for SPF and verification codes, and NS to find which provider actually controls the zone.
After You Change a Record
Changes spread as resolver caches expire. The DNS Propagation Checker asks several major public resolvers for the same record, and the TTL Checker shows how long old answers may be cached. For security, the CAA Record Lookup shows which certificate authorities may issue for a domain, and the DNSSEC Checker confirms signing is set up. Our DNS records guide explains each type.
