/48 for work (actually I have six of the bloody things!) and /56 for home which is reasonable. /64 is ridiculous unless they will give you more on request but then why not /56 so you can plan. We really are not going to run out of those and even /48 for all is pretty reasonable. At work I have an additional /64 just for WAN but I understand /112 and the like are popular for that as well.
I suggest you have a play with the /64 just for fun and to get the hang of things but the future has a shed load of IoT in it and all networks will need breaking up into subnets for security, including residential networks. Even if only to separate guest wifi.
In the UK we have the relative luxury of being able to choose from a fairly long list of ISPs. Some of them nearly get IPv6. Funnily enough dear old BT (business) is one of the few that gets it all correct out of the box, when you order a leased line.
You have my sympathies.
- jrockway 7y ago/64 is a lot of addresses. That's 2^32 internets.
- darkr 7y agoBut it’s only a single subnet or point-to-point link, you can’t do anything interesting with that space
- jandrese 7y agoWhen you see an IPv6 address mentally block out the last 64 bits. A /64 in IPv6 land is the equivelent of a single public IPv4 address for most practical purposes.
- borumpilot 7y agoI would prefer to "A /64 in IPv6 land is the equivalent of a single public IPv4/24 for most practical purposes."
- jandrese 7y agoBack in the 80s or possibly 90s that might have worked, but an experienced admin today will look at a /24 and go "I can support 16 sites with that", whereas a /64 is really the smallest allocation you should see with IPv6, like a single IP address in IPv4.
