Cname Vs Alias Records Easydmarc The differences between cname and alias dns records have more to do with how they resolve queries for the target dns record (for example, anotherdomain ) and certain restrictions or advantages. let’s take a closer look. resolving domain names. cname records differ from alias records in resolving domain names to reach their destination. What is an alias record? unlike an a record, an alias record resolves a domain name to another domain name— not an ip address. alias records work the same way as cname records, except they can coexist with other dns records. cname records are used for subdomains while alias records are used for root domains.
Cname Vs Alias Records Easydmarc Cname and a records are often confused with each other, but there are differences. first, an a record can only connect the primary parent domain to the corresponding ip address. on the other hand, cname records link the parent domain to its alias or subdomains. in other words, cname records can point to other cname records or a records but a. The chief difference between a cname record and an alias record is not in the result—both point to another dns record—but in how they resolve the target dns record when queried. as a result of this difference, one is safe to use at the zone apex (for example, naked domain such as example ), while the other is not. Great answer 🙏 extra note that cname is an official dns standard record type, whereas alias is a non standard custom one implemented by dns providers (to make up for shortcomings of cname). more discussion on it here. While both cname and alias records serve similar purposes of aliasing one domain to another, they differ in their capabilities and use cases. cname records are suitable for aliasing subdomains and redirecting traffic within a domain, while alias records offer greater flexibility, particularly for directing traffic at the apex of a domain and.

The main difference is that a single cname record can only reference a single domain name, whereas multiple alias records can reference a single domain name at once. in addition, alias records only redirect a records and aaaa records, meaning they do not conflict with other record types like txt records and url records. What are cname records? a canonical name (cname) record maps one domain name to another, allowing alias domains or subdomains (like blog.example ) to be mapped to a primary domain (such as example ). a cname record for an alias domain can map to another cname record or to a domain name with an a or aaaa record. Cname records, which map an alias to a canonical domain, significantly affect dns records, especially for email deliverability. txt records like spf, dkim, and dmarc are generally preserved, but mx records must point to a records, not cnames, to avoid delivery failures. Cname vs. alias the alias record is similar to the cname but has distinct properties. while the alias record also connects a hostname to another hostname, it allows you to have other dns records on the same hostname.
