Take back control of your traffic with GeoFilters. You decide who can access your site and who can't based on their location, IP address (IPv4 and IPv6), ASN (Autonomous System Network), or EDNS client subnet.

  • Filter out malicious traffic sources by dropping any lookups that match your GeoFilter rule. This service is a first of its kind, providing you with a DNS level firewall to combat DDoS attacks.
  • Need to deliver location specific content? Set a GeoFilter rule to include or exclude particular regions or cities.
  • Great for retailers with location specific sales, ad delivery, and much more.

Use our GeoIP engine to automatically calculate which servers are closest to your end-users for the fastest response.

Narrow down your targeting from regional, to as granular as city level lookups! You can also specify the longitude and latitude of your lookups.

Learn How to Use GTD

GTD with GeoIP Services

This method actually corrects any errors caused by incorrect IP to Location mapping databases; as well as incorrect GTD lookups by poor peering practices; and can effectively detect outliers better than the competition.

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

Double Down

Combine GeoFilters with GeoProximity! As long as your GeoFilter rules are matched first and then GeoProximity rules are matched second.

The Future of DNS

Recent trends show that end-users prefer when their experience is personalized. GeoFilters can be used to deliver tailored content that's specific to a user's location.

Real-Time Responses

GeoIP responses are centered on an IP to location lookup that are done in real-time and are configurable with ANAME, CNAME, and AAAA records.

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.
