I'm curious. Where does OS X keeps its hosts file?

In Netinfo:

This is only semi-true.
(The article is a collection of all possible techniques, and despite it's recent date, does not have correct information for release 10.2, aka Jaguar.)


OS X has always "supported" /etc/hosts.

In different releases of the OS, the technique to read /etc/hosts differed. (see the article.)

In the early versions, you had to load the contents of /etc/hosts into netinfo because netinfo was the only place the resolver (lookupd) looked.

In later versions the resolver could be configured to look in /etc/hosts in addition to the Netinfo database.

However, as of 10.2, /etc/hosts is consulted automatically along with any configured LDAP servers. No modifications to lookupd or netinfo are necessary.
