Many of the existing internal networks are using private, non-routable IPv4 ranges. And exposing random hosts on the internet is a bad practice, security-wise. The only things that needs routable IPs are VPN endpoints and load balancers.
Together, that means there is no need to ever get rid of IPv4 on the internal networks. Yes, maybe the workstations will have IPv6 for random website access, but that old NAS box will always be at 10.1.2.3.
- yesco 5y agoI agree with you, but I'm not sure why this would be relevant?
- theamk 5y agoThis was re your "IPv6 is inevitable" comment -- we can get pretty far with IPv4. In particular, as long as you keep using third-party load balancers, you could probably keep using it for decades. And you may never have to migrate your internal infrastructure at all.
