Yes, /etc/nsswitch.conf. Make the "hosts" entry say:
hosts: files dns
...unless you are using nis.
You also need to do "nsadmin restart" or reboot after making modifications
to nsswitch.conf or resolv.conf.

The Apache 1.3.6 webserver that the CCP14 uses should now be happy,
even if you are browsing via network links with
Lame or Misconfigured DNS servers. It looks like the cause of
the erratic Apache problem was compiling up Apache 1.3.6
using a GCC compiler inheritted from a previous version of
the IRIX operating system on the SGI O2 server. Thanks for
Drazen Kacar (E-mail: dave@fly.cc.fer.hr) for helping to confirm this.
"If I decoded this correctly, you want to say that you have gcc compiled
on old version of IRIX. This is bad. Very bad. Gcc wants to have its
own include files and some of them depend on the things you got with
the OS. In general, when you use gcc compiled on a previous version
of any OS, weird things can happen. Since everything's OK with wget
produced with a native C compiler, I suppose weirdness you've
discovered can be attributed to the improper gcc setup."
Note of April 1999 - changing compilers does not seem to help things.
Note of ~20th April 1999 - Turn off DNS Hostname lookup to avoid the DNS problem
Note of ~1st May 1999 - The "/usr/local/apache/bin/logresolve" program seems to hang
trying to resolve IP addresses to names - thus may have something reproduceable to work with later.
Note of 6th May 1999 - Re problem with DNS lookup and Lame DNS servers with Apache 1.3.6
Based on a post on comp.sys.sgi.apps (Title: Re: Ping #'s not names?) reconfigure the "nsd" - UNS name
service deamon which might fix the problem due to the default installation not having the required
option in the nsswitch.conf. (I think the reboot means "chkconfig restart"). Try testing using the
Apache "logresolve" program.
