- gowld 8y agoIs it possible for IPv4 to not recycle IPs? Is IPv6 big enough to not recycle IPs in the modern high-churn deployment world? (It's probably big enough to give every human (or payment card holding customer) a few million blocks of IPs that they can personally control, and recycle IPs within each accountable block that)
- mirimir 8y agoFor IPv4, clearly no, at this point. For IPv6, clearly yes, at least so far. It's pretty typical to get at least a /64 aka LAN with a VPS. That's 18 x 10^18 addresses. ISP customers typically get a /56 (256 LANs) or a /48 (65536 LANs).
