No backup service of any sort - plain straight forward FTTP with v4 & v6. No proxies, VPN, CGNAT or anything. PPPoE to router/switch and out to various APs.

Over time, it has seen various different ISPs and v4 addresses ...


Not really too worried about it as I was getting what was expected. I don't kogon so nothing is logged or stored and I believe at one point two PCs had different ISPs and v4 addresses shown!
