LXC Networking - No hostname from nslookup?

Strange question, and honestly not a big deal, but just got me wondering.

When I do an nslookup or a ping -a xxx.xxx.xxx.xxx, my plex LXC doesn't return a hostname. My router shows its name as UNKNOWN (where other IPs would show a hostname), even though I've confirmed the hostname within the LXC is "plex".

Does anyone know how I might go about fixing this, or at least the cause?

EDIT: Digging, I'm thinking it's the reverse name resolution that's failing, so I'm digging into that.

Just a guess, but do you have an entry in your DNS server for the plex instance? Since nslookup is going to query your DNS, I would look there for any inconsistencies.
