NETWORK TOOLS
DNS lookup
Check the DNS records for any domain: A, AAAA, MX, TXT, CNAME, NS, SOA and CAA. Enter an IP address to see its reverse DNS.
What it shows
Every public DNS record for a domain, straight from the authoritative servers, so you can check where a website, email or service is pointing.
When to use it
After changing nameservers or moving a website, when email isn’t arriving, or to check a verification TXT record has been added correctly.
Changes not showing?
DNS changes can take time to spread because of caching. The TTL column shows how long, in seconds, a record can be cached.
