When you go to allow your IP via the security section in STORM you may see an unusual IP pre populate the IP Adress field. This is likely to be an IPv6 address.
What is IPv6
IPv6 is the most recent version of the Internet Protocol, the communications protocol that provides an identification and location system for computers on networks and routes traffic across the Internet. IPv6 was developed to deal with the long-anticipated problem of IPv4 address exhaustion. IPv6 is intended to replace IPv4.
IPv6 addresses are represented as eight groups of four hexadecimal digits with the groups being separated by colons, for example 2001:0db8:0000:0042:0000:8a2e:0370:7334.
During the transition from IPv4 to IPv6, it is likely that your ISP will provide you with both an IPv4 and an IPv6 address.
Which IP should I allow?
It is possible for you to connect to your STORM server via your IPv4 or your IPv6 address so it is important that you allow both addresses. The link below will show the addresses that you have been assigned by your ISP. Please add both addresses to the allowed IP list.
