IP changing, block of 6 lost

I escaped the last round where Zen moved IP addresses so they could flog off blocks of IPv4. Today they say I'm getting a new IP in August and I'm losing my block (cos I don't pay).

To be fair I've never used the block so I won't miss it. The IP address moves from 82.68.x.x to 82.71.x.x. My only regret is I've used my current IP for a mailserver without trouble for years, hopefully the new address won't be on any blocklists.

I guess if I really need other addresses I could get my head around IPv6.

Anyway, hours of endless fun ahead as I reconfigure all my DNS forwards, VPNs and all the other stuff I can't remember untill it all goes down...
