DNS Lookup
Look up DNS records for any domain. Check A, AAAA, MX, NS, TXT, and CNAME records.
Understanding DNS Records
DNS (Domain Name System) is the phonebook of the internet. It translates human-readable domain names like google.com into IP addresses.
Why check DNS records?
Verifying your DNS records is crucial for ensuring your website is accessible and your email services work correctly. Incorrect DNS settings can lead to downtimes and email delivery issues.
Common DNS Issues
Common issues include missing MX records (email failure), incorrect SPF/DKIM records (email security), or old A records pointing to previous servers (downtime).
DNS Record Types Explained
A Record
Maps a domain to an IPv4 address (e.g. 192.168.1.1). Essential for website hosting.
AAAA Record
Maps a domain to an IPv6 address. The modern standard for IP addressing.
MX Record
Mail Exchange record. Specifies the mail server responsible for accepting email messages.
NS Record
Nameserver record. Indicates which DNS server is authoritative for your domain.
TXT Record
Text record. Used for verification (SPF, DKIM) and security configuration.
CNAME Record
Canonical Name. Maps one domain name to another (alias). Useful for subdomains.
