@noodles my ISP (the awesome #zeninternet ) gives me a small IPv4 block for free, and I've never done much with it. Better to setup and not need than the reverse I think
If you are with Zen Internet and have multiple IP addresses then check your spam folder as they've been bulk emailing out telling people that have 8 addresses they will be removing that.
Having checked the contract I have from 2017 I've replied with a formal complaint, and notice of breach of contract, along with a list of reasonable expenses that such action would occur so their lawyers can't argue they were not forseeable.
Hooray! I emailed Zen Internet yesterday having moved to them from BT and today they've enabled #IPv6 on my connection.
I have no idea why they wouldn't enable it by default but it's working perfectly and now I have a /48 (1 septillion addresses) to use for...something...
