For the longest time, the default ArchLinux networking setup had one
deficiency:  it would not send the machine hostname to the DHCP server
/ router when acquiring a DHCP lease.  As a result, I was never able
to ping/ssh my ArchLinux system by its hostname from other machines in
my home network --- instead, I was always forced to type out my
ArchLinux system's IP address in full.

I looked high and low across the 'net before I finally found the
answer in the dhcpcd.conf man page:  the solution is to add the
following line to your /etc/dhcpcd.conf file:


One thing that confused me is this line in the default ArchLinux
/etc/dhcpd.conf file:

  # dhcpcd-run-hooks uses these options.
  option domain_name_servers, domain_name, domain_search, host_name

The "option host_name" part *seems* like it would send your machine's
hostname to the DHCP server, but it really doesn't.  Maybe that's a

I request the developers in charge of the default ArchLinux networking
setup to make the above change, so that ArchLinux systems send their
hostnames to the DHCP server (and therefore can be
pinged/ssh'ed/accessed by their hostname) out of the box!

Thanks for your consideration.
