What is fnAdminMask?

This object reports the prefix length, or subnet mask, paired with an administrator account's allowed source address, together defining the exact network or host range that account may log in from. An administrator reviews this alongside fnAdminAddr to confirm how tightly an account's management access is scoped. A prefix length of 32 paired with a single address would restrict that admin account to logins from that one specific host only.
