What is GeoDNS?

GeoDNS is a powerful set of tools that allow you to determine how end-users will reach your domains based on their location (or other unique attributes).

You can use GeoDNS to create rules that permit or prevent specific users from accessing your content. For example, you can use this technology to:

  • Build your own Content Deliver Network (CDN)
  • Geographic load balancing
  • Block malicious or unwanted traffic
  • Optimize routing for different networks or regions

DNS Firewall

Block or target traffic by location

Available for A, AAAA, CNAME, and now ANAME records.

  • Firewall at the DNS level that allows you to block maliciouis traffic before it even reaches your servers.
  • DNS-level rules for location specific content
  • Great for retailers with location specific sales, ad delivery, and much more.

Supercharge GeoIP Services with GTD

This method corrects any errors caused by incorrect IP to Location mapping databases from GeoIP services (IP Filters and GeoProximity); as well as incorrect lookups by poor peering practices.

Constellix is the only platform that offers these two services together, giving you the most accurate configurations in the industry. (Patent pending)

GeoDNS with EDNS Client Subnet

Our GeoIP servers use EDNS-Client-Subnet to give you the most accurate response based on the actual location of your IP (as opposed to the closest regional server). Additionally, the Geo backend can be used to provide service over several clusters. Any of which can be taken out of use easily, say for maintenance purposes.

Ask your resolver if they support EDNS and learn how you can start creating even more precise configurations. Constellix has established itself as the industry leader in EDNS offerings, and encourages resolvers to consider adopting EDNS technology for greater accuracy.

These features can be defined on a per record basis to ANAME, CNAME, and AAAA records.
