Guys,
What is the proper entry for 127.0.0.1 in /etc/hosts?
My systems all have:
127.0.0.1 localhost
I have seen discussion that 127.0.0.2 is deprecated
Like John says, 127.0.0.0/8 are usually assigned to the loopback interface, and are usually = localhost.
Well, The documentation shows (man hosts): IP_address canonical_hostname [aliases...] showing you can have any number of aliases for a given IP_address canonical_hostname pair. So I have always included the hostname as an alias after localhost: 127.0.0.1 localhost phoenix which provides resolution for localhost as well as your hostname on loopback. I have run across several web apps that want to be able to resolve the loopback address with the hostname. The 127.0.0.2 SuSE has used is a hack and there is talk about doing away with it completely. The real problem is with dnsdomainname (or hostname -d) which will not resolve to anything unless you include the full canonical_hostname in /etc/hosts: 127.0.0.1 providence.rlfpllc.com localhost providence This works fine for dnsdomainname (or hostname -d). Also, since it provides the definition for localhost on loopback, it does what it is supposed to as far as I can tell. I can't see any downside to this approach, but I'm skeptical enough to ask and see if anybody else knows of any gotchas or side-effects from doing this? -- David C. Rankin, J.D.,P.E.
