If your university doesn't have a lot more demand for IP addresses then yeah -- it makes sense that they'd just hold on to their network space, continue to NAT their DHCP pools and keep doing what they're doing. That's not an indictment of IPv6, it just means that the work to deploy IPv6 doesn't provide any benefits to them. However, newcomers and networks that foresee expansion can't just "stay the course" -- there just isn't enough IPv4 for them -- and do need to bite the IPv6 bullet. Deploying IPv6 does indeed require work in terms of management (all tools that assume the length/format of an IP address need to be updated, netadmins need to learn and deploy RA guard and friends) and your network silicon needs to do IPv6 in the fastpath -- but even with all these pain points, carrier-grade NAT'ing IPv4 is nevertheless more painful, expensive, and slow. Forward-thinking network operators have been taking advantage of the LTE and DOCSIS 3 transitions to enable native IPv6 everywhere, and Facebook is moving to IPv6-only infrastructure -- and it's paid off! About 80% of network traffic (to Akamai) from T-Mobile and Verizon is IPv6 (from Comcast it's lower -- around 50%): https://www.akamai.com/uk/en/our-thinking/state-of-the-internet-report/state-of-the-internet-ipv6-adoption-visualization.jsp https://www.akamai.com/uk/en/our-thinking/state-of-the-inter... The future is IPv6 -- it's just not quite equally distributed yet.
