What are the main issues with IPv6?
Edit: I did not mean this as a derogatory question. It's legitimate. I simply posted it under the wrong OP. Calm down people.
- alex_hitchins 9y agoSorry, I'm not sure I follow your question.
- ulzeraj 9y agoIMO retarded greedy ISPs issuing /64 prefixes to customers. Now you aren’t supposed to NAT but you can’t have multiple subnets either.
- ceejayoz 9y agoNot a network guy, but I thought IPv6 made subnetting mostly unnecessary? Certainly on an individual consumer level?
- zAy0LfpBZLC8mAC 9y agoA subnet is simply a range of addresses assigned for a particular layer 2 network. Not having a subnet is equivalent to not having addresses ... that does not really make sense.
- ceejayoz 9y agoWell, obviously you need one... I'm asking about multiple. IPv6 doesn't have broadcasting, and you've got 18 quintillion IPs in a /64, hence my question.
- zAy0LfpBZLC8mAC 9y agoWell, if you have multiple layer 2 networks, you need multiple subnets, and you should assign a /64 per layer 2 network for stateless autoconfiguration to work, so splitting a /64 into smaller pieces is not a good idea, therefore an ISP should give you at least a /56, better a /48, that you can subnet for any layer 2 networks that you might have.
- ulzeraj 9y agoReal life example: how do you isolate a wireless guest SSID from your main work network without different subnets? Those are still needed but said ISP will just hand you one network.
- wolrah 9y agoMany wireless APs have a "guest filter" mode which prevents devices on the guest SSID from communicating with the LAN outside of DHCP and optionally other approved services. I use this on my home LAN, guests can communicate with the Chromecast and media server but can't reach the printer or others.

- ChristianBundy 9y agoThe only "issue" with IPv6 is that it requires that your provider spends time and money upgrading.
