Thanks for your response. Requested output is as below.
Note that there are two telnet attempts below. The first is using the hostname and the second is using the IP address. I was expecting both to behave the same, i.e., use the /etc/hosts file entry but that does not seem to be happening.
The first telnet using the hostname is connecting via the DNS and the second telnet using the IP address is connecting via the /etc/hosts file. This is my assumption. I can tell that the first telnet is using the one from the DNS server because I don't see the HP-UX banner while the second telnet attempt is showing the HP-UX banner. The HP-UX server is the one that am wanting to connect to.

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.
