Check the interfaces to ensure they have the proper netmasks and default routes;

I found some systems with the main interface configured as a /32 it's
top of mind lately.

That is not necessarily a problem - it entirely depends on their setup. I prefer my Ceph clusters (any cluster, really) to be routed, so we have *only* /32s
(besides the management network that is a flat /24 or /16).

If it was designed with routing in mind, an all hosts have /32s, I don't see
any issue with that.

Else, of course, you are right, mixing netmasks is never a good thing.
