How to alias a hostname?

hosts networking alias dns

A slightly less convienent way is to set up aliases for both ping and ssh, for example:

alias pingfoo="ping foohost.domain.tld"

OpenSSH supports adding hostname aliases (and many more options) to ~/.ssh/config:

Host foo
    Hostname foohost.domain.tld
    # You can also add User, Port, every possible ssh(1) option.

With dnsmasq's option --cname=<cname>,<target> you can make a CNAME that indicates that <cname> is actually <target>. Note that this works only if the DNS name of <target> is known to dnsmasq (either in hosts file or through DHCP).

If dnsmasq doesn't work, Unbound is a DNS resolver that supports also unknown targets in a similar situation.
