Each DNS record holds important information or instructions that tell DNS servers what to do for a domain. Records can help you customize your domain’s web traffic and behavior, provide security benefits, and more, but as they each have their own purpose, options can be somewhat limited when it comes to certain functions.
One of the most used DNS records, aside from an A record, is the CNAME record. This record lets you point multiple hosts to a single location. One major restriction with CNAME records is the inability to point to the root of a domain.
How to avoid CNAME record restrictions
ANAME records solve this problem.
If you want CNAME functionality at the root of your domain, you can configure an ANAME record. This is especially beneficial for mission-critical applications, content delivery networks (CDNs), and multi-cloud environments. Constellix’s ANAME records have the most geo-accurate functionality out of all alias-type records in the industry and work with all of our GeoDNS and Multi-CDN solutions.
