DNS CNAME Record
Sitecheck Team
Aliases one hostname to another hostname.
A CNAME record maps one hostname to another hostname (an alias). The target must be a hostname, not an IP address.
Why it matters: CNAMEs simplify DNS management by pointing multiple subdomains to a single canonical hostname.
Quick tips:
- Do not use a CNAME at the root (apex) unless your provider supports it.
- Avoid chaining multiple CNAMEs to reduce lookup time.
