Find DNS alias targets for a hostname
Discover the canonical name behind a DNS alias.
Type a hostname to check CNAME records.
CNAME records map an alias hostname to a canonical hostname, making it easy to point multiple names to one target.
Use CNAME for subdomains, CDN endpoints, or services that should follow another hostname.
Root domains typically cannot use CNAME. Use A/AAAA or ALIAS/ANAME records instead.
Resolve the canonical host to IP addresses.
Compare all record types in one view.
No. A hostname with a CNAME should not have other record types at the same name.
The hostname may not be an alias, or the record may be published on a subdomain instead.
Short chains are okay, but long chains can slow resolution and may be limited by resolvers.
