Open tool →Why use these tools?
When you launch or move a website, most problems come down to the same few things: the domain is about to expire, the nameservers are wrong, a DNS record has not updated, or the SSL certificate is missing or expired. These tools let you check each of them in seconds, from any device, without installing anything.
- Before buying a domain: run a WHOIS lookup to see if it is taken, who the registrar is and when it expires.
- After pointing a domain to hosting: use the nameserver checker and DNS lookup to confirm the change.
- When your site shows a security warning: use the SSL checker.
- When you want to know where a site is hosted: use the IP & hosting lookup.
Lookups use public information only. Results are cached for a few minutes and usage is rate limited to keep the service fast for everyone.
