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?
A lot of networks were designed with ipv4 and NAT in mind. There really isn’t a cost benefit to migrate all your DHCP scopes, VLANs, Subnets, and firewall rules to IPv6 and then also migrate 1000’s of endpoints to it.
Much cheaper to just disable ipv6 entirely on the internal network (to prevent attacks using a rogue dhcpv6 server etc) and only use ipv6 on your WAN connections if you have to use it.
