Manage IPv4 Exhaustion Now.

ISPs and other broadband service providers, mobile network operators, web hosting and cloud hosting companies face a challenge—How to manage growth with their existing and extensive IPv4-based investments while taking a long-term approach to seamlessly migrate to IPv6.

A10 Thunder CGN helps regional service providers extend their investment in IPv4 infrastructure while creating a path to eventual IPv6 migration.

As we continued to grow, we needed more IP addresses. But the price associated with purchasing IP addresses on the secondary market was not cost efficient for us…. With Thunder CGN…we are able to extend our network and allow our company to continue growing in a way that is cost effective.”

-  Michael Robinsons, System Engineer  |  MCTV

IPv6 – Are We There Yet?

Learn how you can extend the utility of current IPv4 addresses and bridge the shift from IPv4 to IPv6 with a lifecycle strategy that meets both short-term growth needs and long-term requirements for your subscribers and business.

A New Generation is Arriving—But Not All at Once

IPv4 addresses have been exhausted and open-market prices are skyrocketing.  Long term, IPv6 will need to be implemented. But until every end user and content provider makes the switch, you’ll still need to support both IPv4 and IPv6 servers and applications.
