People still working in IT, thoughts on IPv6? (lemmy.world)

Now currently I'm not in the workforce, but in the past from my work experience, apprenticeship and temp roles, I've always seen ipv4 and not ipv6!

Hell, my ISP seems to exclusively use ipv4 (unless behind nats they're using ipv6)

Do you think a lot of people stick with the earlier iteration because they have been so familiar with it for a long time?

When you look at a ipv6, it looks menacing with a long string of letters and numbers compared to the more simpler often.

I am aware the IP bucket has gone dry and they gotta bring in a new IP cow with a even bigger bucket, but what do you think? Do you yourself or your firm use ipv4 or 6?

Ipv6 does simplify routing. It has less headers and therefore less overheard. IPv6 addressed the necessity of NAT by adding an obscene amount of possible IPs. Removing the necessity of NAT also simplifies routing as it's less that the router has to do.

Ipv6 as a concept was drafted in the 90s. It didn't start actually being seriously used until ~2006/7ish.

that is correct but doesn't change the fact that nat came afterwards as a workaround und now the ip stack goes back to it's roots without a nat workaround.

true but still nowadays it isn't even slow anymore just refusal

That's just the pace of large scale adoption of new technology. Look at some of the technologies the banking and financial industry uses as an example (ISO 8583 is a great example). ISP's still support T1 circuits as well.

There are other benefits of NAT, besides address range. Putting devices behind a NAT is hugely beneficial for privacy and security.

NAT is not a security feature. Your firewall blocks incoming traffic, not NAT. It introduces new complexity that now needs to be solved.

In corpo environments you have to struggle with NAT traversal for VoIP communication.

In home networks "smart" devices attempt to solve it with shit like uPnP and suddenly you get bigger holes in your network security than before. You could find countless home network printers on shodan because of this. Even though (or maybe because) they were "behind" NAT.

IPv6 has temporary IPs for privacy reasons. NAT is NOT a firewall. Setting up a real firewall is more secure and gives you more control without things like UPNP and NAT-PMP.
