Not having to buy IPv4 addresses. CG-NAT infrastructure expenses scale up with customer base. If most of their traffic is end to end IPv6 that's a savings. End point machines like cable modems, TV decoders, VoIP adapters/IP phones, all need their own IP address; service providers with more than 16.7 million managed devices attached need IPv6.
- pbhjpbhj 8y agoBut do the ongoing CGNAT expenses outweigh the potential expenses of transitioning? I'm with one of, if not the, largest UK ISP and am pretty sure they're not IPv6 ready because their routers have no mention of it (Huawei router firmware updates presumably needed). BT have upgraded the physical infrastructure so I'd expect we'd be there already if there were easy savings.
