Q: Multiple IP Address Entries Listed for OD Master

My Open Directory server is running well, but I have a question about the first table that shows up in the Open Directory section of the Server app. The Server Name and Type are correct, but the Addresses field has 5 IP addresses listed, two of which I do not recognize and one of which is a duplicate:

I’ve obfuscated potentially sensitive information, but the first entry is a valid and functioning FQDN for the OD Master. The first and last IP Addresses listed on the right side are actually the same address (this is the address that the FQDN resolves to, and PTR record for this IP resolves to the FQDN). I have no idea why it’s listed twice and I don’t know if I should be concerned about that. Checking the IP returns a green light:

$ sudo changeip -checkhostname

dirserv:success = "success"

The second address (172.16.32.1) is the IP address for the server’s virtual interface that the VPN Server uses, so that one is expected. The third and fourth entries, however, are unknown to me and I’m not sure where they would come from. Those two addresses are on the private 172.16.0.0/12 block, so they’re un-routable.

Is there a way to update or remove these errant addresses from my OD server config? Should I be concerned about them? What about the duplicate entries for the actual IP?
