Thank you for opening a bug report. Unfortunately, the information you have provided is not sufficient for someone else to attempt to reproduce the reported behavior. Remember, each bug report must include detailed steps that someone else can follow on a clean, empty NetBox installation to reproduce the exact problem you're experiencing. These instructions should include the creation of any involved objects, any configuration changes, and complete accounting of the actions being taken. Also be sure that your report does not reference data on the public NetBox demo, as that is subject to change at any time by an outside party and cannot be relied upon for bug reports.

I'm not really sure what else I can provide here to give more detail, it's (for me at least) trivial to reproduce.

  1. Have a working v3.1.2 install.
  2. Upgrade it to v3.1.3.
  3. Unable to edit IPv6 prefixes due to the address length overflowing the max integer size.

I'd guess it's due to the new address overview panel but I've had to roll back to 3.1.2 so it's only a guess.

Editing any sufficiently short IPv6 prefix say 2001:db8::/64 throws the error. A /126 does not have the error.
