Agreed, lots of (relatively) old switches support IPv6 management
addresses without issue. My suggestion is to dedicate a nibble in
your IPv6 numbering plan for loopbacks/mgmt addresses, firewall
access to this nibble as necessary, and go to town.<br>

I don’t see much difference between v6 management addresses and v4
management addresses when it comes to best practices.

<div class="">I will say that if it were my network, I’d move

<div class="">Once you’ve got the ability to use IPv6 management
