Please note we are no longer leasing new static IP addresses.

Devices on the internet use IP addresses to locate and talk to each other, much the same way we use phone numbers or e-mail addresses to talk to or send electronic messages to specific people.

There are two kinds of IP addresses: static and dynamic. Static means the address doesn't change, and dynamic means it does change.

IPv6 is the latest version of the Internet Protocol (IP) that is the basis of how the internet is built and how it runs.

The internet was originally designed using IPv4, but after several years of enormous growth, it started to look like the world would run out of IP addresses. In 1998, IP version 6 (IPv6) was standardized. Simply put, version 6 gives the internet more IP addresses and additional features.

All IPv4 addresses typically have a "derived IPv6 address" associated with them.

When you lease a static IPv4 address, those addresses have 'derived IPv6' addresses associated to them, so there is no need to order anything else. But, you will need to enable IPv6 on your modem.

Yes, the two types have different strucures.

IPv4 addresses contain only numbers in groups of two or three, separated by periods, like this: 62.157.9.98

IPv6 addresses use 4-digit groups of letters or numbers, separated by colons, like this: 2002:3e9d:9062:0001:1

To troubleshoot IPv6:

Make sure your modem is IPv6 capable. If IPv6 is not listed in the features section, chat with customer service to review your options.
Enable IPv6 on your modem
Test your IPv6 connection
