I would expect this behaviour as this is probably a virtual Web server in
apache (or any webbserver) configured just for jwchat.
If you check http at Wikipedia you'll see that the client sends the wanted
server name as parameter "host: " in the GET request to the Web server.
This is used to select the right Web server.  The solution with mDns is
probably the most useful one, and not only for this.

Yes, this is what I would do for an easy installation without the need to
configure the local name server in the LAN(in the home router). The DHCP
client in the freedombox should also publish its preferred name and then
the LAN router usually uses that in all name resolutions in the LAN too.
But if not, mDns is also used.
