> The fundamental reason for having IPv6 got broken over a decade ago, and people stopped bothering because it had no benefits over what exists now.
So you think that only big companies with lot of money can have servers and that users are just users, will never need any server, can be all behind NAt
you think that a centralized network is ok... exactly now, where Mobile and IoT devices are everywhere and that peer2peer connections could be even more useful for future developments, but everything is behind NATs. Firewalls also exist in ipv6, that makes no difference to ipv4... and nat is not a firewall, by the way!
> It still has use - it does have a larger address space, but that's the only benefit it added.
I directly pointed that IPv6 have other benefits other than more IPs, but yep, you ignore it... quick list:
- simplify the IP headers, faster and easier processing the packages
- IPSec is now default and everything can use it, think https but for all other protocols
- roaming networks
- security/privacy, you can enable privacy extensions and each connection will use a different IP, making tracking and profile much harder
- easier routing and easier for routers and backbones to manage all the traffic
- automatic configuration, while dhcpv6 can still have it uses, you can deploy a network without it, dhcpv6 is also much simpler, no ARP and other legacy junk, it now just give you the DNS, NTP and other info, the IP is mostly autoconfigured
- ipv4 is already limiting IoT, requiring everything to talk to a central server, ipv6 can allow a true independent setup. Both autoconfigure, more IPvs, IPsec can build sub networks for this services. Also, no more having all your devices in the same ip range, you can have multiple, automatic, subnets, improving security
- you have localhost, localnet (never exist routers, perfect for internal networks) and internet... so you get a extra network that is very usefull (and replace most of what people say they want a NAT setup)
> Also, IPv6 purists are just nasty to work behind. IPv6 would replace everything you need - no need for DHCP, NAT, etc anymore i IPv6 does it all.
You even say that dhcpv6 and natv6 exist! nobody stop you to use them!!
dhcpv6 is actually used in many ipv6 setups. nat, while there are used for it, most people that want it, confuse nat with a firewall and, again, nat is not a firewall. Most people that say they want natv6 don't actually need any nat
> Not an entire family behind a single IPv4 address, when you can have every kid's phone having a unique IP so you can sue just the kid.
you don't know the ipv6 features, so you don't know the privacy extensions. It actually makes impossible to know what device did the connection, specially because there is no record in automatic configuration, no arp, etc. it makes much harder to prove the real source of the request
your car example make a good example of what ipv6 allow...
your car can connect to a central server and report any problem, but you can also query your car to check its status and request other car service company to connect to your car, check the status and have quick maintenance check without having to take your car to the anyplace.
