I've yet to come across a home gateway that handles name resolution, they just dole out numerical IPs from their DHCP server, it also seems to be a bit of a rarity for a client to accept a hostname that a DHCP server does supply (if it does). DHCP clients can also request the DHCP server lets them use their own hostname, and that's often ignored, too. More often than not, a client would to a reverse DNS look-up on its assigned IP to see what domain/hostname is associated with that IP (which could be a DNS query, but first it looks in the hosts file). Not everyone has a DNS server, or a configurable one, nor adjusts their hosts file (often fighting with Network Mangler over it). So: > Set your preferred hostname either in GNOME Settings (or whatever > DE’s settings) or with hostnamectl. Which stores a setting somewhere naming itself consistently, whatever IP address you get given. This can get messy if you get assigned different numerical IPs from time to time. -- uname -rsvp Linux 3.10.0-1160.114.2.el7.x86_64 #1 SMP Wed Mar 20 15:54:52 UTC 2024 x86_64 Boilerplate: All unexpected mail to my mailbox is automatically deleted.
