Re: Public or Private IPs

Ohio State started its road from IPv4 public to IPv4NAT+IPv6 dual-stack ~3 years ago. We started out of necessity: we were running out of /23s to add to our existing VLAN pools. We leveraged ClearPass to isolate phones/tablets using student credentials (largest population) and started putting them into IPv4NAT /20s frontended by a public /25. After that success, we ended up putting all student devices in that same pool. Overtime, and with our upgrade to ArubaOS8, we've migrate ~90% of our client base to IPv4NAT+IPv6 dual-stack. The only remaining population is our internal LAN for colleges/units that use central IT for all IT services. I won't be surprised if this pool is migrated as well.
