Virtual Hosts and Alteon DNS conflicts

Hi,

This is more of a verification rather than a question of technical nature.

This is based on solaris 10 machine

Could we use Virtual hosts (within our hosts file):
123.1.1.10 virtual_host_name
123.1.1.10 host_A
(note: 123.1.1.10 - host_A is also in our DNS server entry)

And also have alteon switch pointing to (222.1.1.2) to the same name 'virtual_host_name'? (matched as such in the DNS server entry)

That is 2 different IP's using the same hostname.

What is also we added a second server (with hosts file):
123.1.1.20 virtual_host_name
123.1.1.20 host_B
(note: 123.1.1.20 - host_B is also in our DNS server entry)

That would make it 3 different IP's using the same hostname.

Just for info. in the nsswitch.conf file, we have put DNS in front of the files:
hosts: files dns

Any help would be much appreciated. If this is not clear and you have questions, please post them, thank you.

DNSSPOOF(8)						      System Manager's Manual						       DNSSPOOF(8)

NAME

       dnsspoof - forge replies to DNS address / pointer queries

SYNOPSIS

       dnsspoof [-i interface] [-f hostsfile] [expression]

DESCRIPTION

       dnsspoof  forges replies to arbitrary DNS address / pointer queries on the LAN. This is useful in bypassing hostname-based access controls,
       or in implementing a variety of man-in-the-middle attacks.

OPTIONS

       -i interface
	      Specify the interface to use.

       -f hostsfile
	      Specify the pathname of a file in hosts(5) format. Only one hostname allowed per line (no aliases), although hostnames  may  contain
	      wildcards (such as *.doubleclick.net).

       expression
	      Specify a tcpdump(8) filter expression to select traffic to sniff.

       If no hostsfile is specified, replies will be forged for all address queries on the LAN with an answer of the local machine's IP address.

FILES

       /usr/share/dsniff/dnsspoof.hosts
	      Sample hosts file.

SEE ALSO

       dsniff(8), hosts(5)
