False meme image that says “bad news ipv4 fans. linus torvalds has announced removing ipv4 support from the linux kernel after the maintainers of the network stack got into a fight over WHAT KIND OF HRT gives the best results. this incident will impact 5 billion people and will make 95% of all network equipment on Earth binnable.” with fake screenshots of the linux kernel mailing list a girl calling another one a slur from 4chan over HRT choices and Linus Torvalds saying he will drop IPv4 support and asking the maintainers to learn to shut the fuck up.
I’ve encountered way too many administrators and network admins who swear that “IPv6 does nothing but cause trouble” but the truth is, the trouble it’s causing is because you can’t half-implement IPv6. You either roll it out to the whole network or you don’t, and the longer you kick that can down the road the harder it’s going to be.
Basically too many professionals who haven’t learned a new technology since 2005 and refuse to try new things keep holding the world back
I don’t even have an ipv6 address, my ISP doesn’t provide them yet. Not much to do about it then lol.
You can maybe change ISP
I think what those admins really mean to say is “We don’t need any of the benefits of IPv6, so IPv4 works just fine and making the large scale change is trouble.”, when you already got your DHCP, NAT, Firewall and stuff up and things do work as expected then you don’t really need NDP or SLAAC.
I will happily enable and use it once doing so doesn’t break any of my connectivity.
I’m not managing an enterprise network, it’s just my home, but my ISP doesn’t support IPv6 so that’s one extra layer of complexity right off the hop. On top of that internal services switch which previously required no manual configuration just seem to randomly not work.
IPv6 is not going to see widespread adoption unless it can be implemented completely transparently for the end user, full stop.
The issue for me is when I have it enabled and try to connect to a site that doesn’t support it fully (same thing / half assed) and the site doesn’t work properly. For home its my wife and kids that complain, when its the office then everyone complains. I get the blame for failed connections or things not working right when a fully compliant IPv6 site works just fine.
Now I am not perfect so It could be me but I have read up and learned as much as possible. No expert but I did deploy DHCPv6 in a test environment. However there is no reason as of yet to deploy DHCPv6 locally since the address space is so wide. Just saying Its possible that the issue is me but from my understanding its like the U.S.A. switching to metric. Parts of us tried it but others didn’t and thus we failed as a giant group.
I think there needs to be a big ass push and force everyone to switch as the same time. I know some of the old devices may not work however those devices have to be 20+ years by now.
If it ain’t broke…
I always bring it up when the network is experiencing problems that they wouldn’t have with IPv6. Running out of IPs in a given scope, increasing costs of public IPs, etc.
“IPv4 is running out of IP addresses so therefore every local network needs to move to IPv6” is a full clown move.
First of all, enterprises usually have at least one public IP (the one I work at right now has more public IPs than they have server VMs)
Secondly enterprises have big enough and complex enough networks to see other benefits of IPv6. For example IPv4 has some problems when broadcast domains are too large, so your internal network sizes are artificially limited when following best practices. Without private networks you don’t have to worry about IP collisions between different private networks that you have to route between (comes up more than you’d think!) etc etc.
