I'm currently with 2degrees but looking at Spark as they have the cheap sky sports deal plus lightbox. My 2degrees connection has a static IPv4 and IPv6 (/56). I currently host a few things on my homelab that require external access and I utilise both my IPv4 and IPv6 static address to achieve this, I'm aware that Spark has not yet got IPv6 running for residential users, so I'd need more than 1 static IPv4... Question is, how many IPv4 addresses can a residential customer have? I'd ideally need 3 until IPv6 comes online for example.
