CGNAT: ROI Calculation

The IPv4 Internet will be around for years, so you will need a way for your subscribers to reach any IPv4-only content on the Internet for years to come. One way to do this is to ensure you have a publicly-routable IPv4 address for every single subscriber, which can get very expensive if you are growing your subscriber base. The cost of IPv4 addresses have been steadily rising, especially as they become more scarce. Carrier Grade NAT (CGNAT) is a much more economical option that allows many customers to share a single IPv4 address. How much can CGNAT save you? Change the figures in the yellow boxes below to get an idea of the cost difference between continually buying IPv4 addresses versus purchasing a CGNAT solution from ZCorum.
