Neither ping nor traceroute query the host you're trying to reach, they too use DNS to resolve the name to an IP.

Originally I had the server at home and on Comcast so I used dyndns.org for DNS.
Once the server got a bit more popular, I leased a server at a colo facility. They set up the server name in their DNS so I didn't really have any reason to manage my own DNS. DynDNS was managing the domains and I... (7 Replies)

Hello!
How do I prevent AIX sendmail from doing a DNS lookup prior sending the mail?
(we still need to have the DNS resolving on AIX level).
We are running AIX 6.1 and 5.3.

desproxy-dns
desproxy-dns(1) User Commands desproxy-dns(1)
NAME
desproxy-dns - DNS for dynamic connections
SYNOPSIS
desproxy-dns dns_server proxy_host proxy_port
OPTIONS
None
DESCRIPTION
If you have direct DNS access then you don't need to do anything else. You know you have direct DNS access if you can resolve host names
to IP addresses.
NOTE: as desproxy-dns listens in port 53 (which is less than 1024) you may need administrator privileges to exec desproxy-dns (in fact if
you are running UN*X, you actually have to run desproxy-dns as root).
OK, so you have a dns server accessible now. But your computer doesn't know anything about that. You must configure your network
accordingly (again, need to be root in UN*X).
Edit /etc/resolv.conf and add the line "nameserver 127.0.0.1". You don't have to restart anything. Just test ping and see if it works.
ENVIRONMENT
None.
FILES
None.
