DNS

Local name resolution is handled by the Fios router. It does name resolution for the domain set in Advanced > System Settings > Local Domain

Things that get 'User Defined' entries in Advanced > DNS Server.

• Devices with static IPs
• dynamic DNS domains that point to my public IP (match the IP to wherever relevant ports are forwarded)
• plex.direct (for plex secure connections)

If a device connects via multiple interfaces the name resolution can break. There isn't a good interface to clear these. One way is to reset the DHCP range (Advanced > IP Address Distribution) to some non-overlapping range, apply settings, then reset it again.
