New IP address range on router

[#1]

When did PN introduced a new IP address range?
Until recently I have always had a 87.xxx.xxx.xxx address, mine is now 91.125.xxx.xxx

Hello Dan,
This IP range is from our Legacy network, which has been combined with the newer one, I assume, due to the lack of IPv4 addresses available.
Its not a "new" range as such.

Matt
Edit Notes: put IPv6 instead of 4
