To Infinity and BEYOND!

Just a quick update. We have new offerings for our DNS clients. We have been hard at work improving the infrastructure and providing development tools to make life easier using Zerigo.

Official Zerigo DNS Ruby Gem

We are pleased to announce the release of an official Ruby gem for our Managed DNS REST API. This gem is fully tested with our production systems and supported by the Zerigo team, as well as open-source (MIT licence).

For more information, refer to the RubyGems page and the github repository

Happy coding. Hit us up in the Gitter.im room for zerigodns or open an issue / pull request if you need help.

Thanks to those original contributors that put it together.

New and Improved DDoS

We have partnered with a premier DDoS services provider to significantly improve DDoS protection. Most users will not need to do a thing to realize the new protection. And we are not changing our pricing structure. We believe any DNS service should provide this level of security and peace of mind as a foundation. This includes our freemium offering as well.


  • Transparent to most users. It will just work.
  • Improved response rates with IP Anycast.
  • Infinitely scalable protection from volumetric attacks.
  • Presence expanded, 5x as many pops as before (30)
  • New regions available (South America, Africa, Austrailia)
  • Existing infrastructure still available.
  • Always On
  • IPv6 Supported

What you may need to do

If you used IP’s to register your name servers with your registrar you will not automatically be protected. You will need to update your records with the new IP’s or leverage alias’ instead.

For your verification here are the old and new values for our a-f DNS pops. Worse case scenario your clients / DNS traffic will continue to leverage our existing infrastructure. If you want the added protection and have hard coded your NS records with your registrar you will need to update them.
