DNS lookup
Enter a domain. We show its A, AAAA, CNAME, MX, NS and TXT records.
What each record type means
A / AAAA records point your domain to the IPv4 or IPv6 address of a server. CNAME records point one name to a different name. MX records route your email. NS records name your DNS servers. TXT records hold SPF, DKIM and verification data.
A DNS change can take hours to become active. If your site is down after a DNS change, check the A record. Then use the website down checker.
Email DNS check: MX records & more
Use this tool as an email DNS checker or an online nslookup for MX records. If the MX records are missing, email bounces.
