Has IPv6 been a failure?
All I know is that IPv4 is still around.
And without knowing the IP Addresses of devices on my LAN, by home network would be harder to manage!
- ndriscoll 3y agoYou can know the IP addresses on your LAN. If you'd like you can assign multiple addresses per interface, so that you have global and local addresses. e.g. local addresses fc00::1 for your router, fc00::2 for your desktop, fc00::3 for your phone, etc. If you want, you can use your global prefix with ::1 ::2 and ::3 for your global addresses too. You don't have to use privacy extensions if you don't want to. Things like peer to peer calling can actually work though without NAT.
- Dylan16807 3y agoAddresses starting with fc are reserved. I would suggest using either fec0 or fd00. Which is still not best practices, but it's a lot closer. (fec0 is deprecated, and fd is supposed to be followed by a randomly chosen 40 bit site ID but you can lie and say your random number was 0)
- ianburrell 3y agofc00::7 is the ULA range. It is not reserved. It is the right range to use for an internal network. There is no reason to prefer fc00 over fd00. fec0 is the site-local addresses. Nobody should be assigning addresses in that range since they are made automatically. Using site-local addresses makes sense for single subnet network like most home networks.
- Dylan16807 3y ago> fc00::7 is the ULA range. It is not reserved. It is the right range to use for an internal network. There is no reason to prefer fc00 over fd00. fc00::/7 is the ULA range. It is made out of two halves. fc00::/8 and fd00::/8 fc00::/8 is reserved. People are only allowed to use fd00::/8 > fec0 is the site-local addresses. Nobody should be assigning addresses in that range since they are made automatically. Using site-local addresses makes sense for single subnet network like most home networks. None of my adapters have automatic fec0 addresses, they only have global and fe80. So can you elaborate on that?
- ianburrell 3y agoI don't know that about ULA range. I got fe80 and fec0 confused. It looks like the latter is the deprecated site-local range. It is unlikely that will be reassigned, but lots of people said the same with IPv4 and got burned. It is safer to use ULA.
- Dylan16807 3y agoAh, yeah, fe80 is automatic but it's link-local so you can't do very much with it.
- ianburrell 3y agoI use mDNS for hosts on home network. They have IPv6 addresses, multiple ones, but I don't care what they are because I have never used them.
- ianburrell 3y agoHacker News added IPv6 support recently. It is quite possible people are using currently using it to access the site. Google has IPv6 support at 50%. Most of the major sites I use have IPv6. Google, Facebook, Amazon, Youtube.
- simoncion 3y ago> All I know is that IPv4 is still around. So what? IPv6 coexists with IPv4 just fine. As has been made abundantly clear over the years, there's no need to have a flag day for a big cutover in order to adopt IPv6.
- 9front 3y agoNo, IPv6 has not been a failure, just a newer version of IP. IPv5 was skipped, so will be IPv7. Maybe IPv8 will unify IPv4 & IPv6.
- CamperBob2 3y agoIPv6 == the new ISDN: I Still Don't Need it... although I will say ISDN was a godsend in the years before my community was finally wired for cable.
- firecall 3y agoWhy the downvotes! It was an honest question!
