I am wondering if anyone of you who knows of the number of IP addresses which I can
assign to 1 Ethernet card (le0)? I am currently using Solaris 2.5 and I believe using
the ifconfig command will allow me to assign more than 1 IP address to the same Ethernet
card.

And by the way, do you know if I can assign an IP address with different Network ID to
the same card? ie. ifconfig le0:1 192.9.9.10 and ifconfig le0:2 192.9.10.10?

Thanks for any responses.

I have a Solaris 2.4 system that has eight IP addresses assigned to a single
e-net interface (le0). Don't know the upper limit.

Seems to work fine. We have two networks on our sub-interfaces, each with different
netmasks.

What is the advantage of doing this? I have two workstations, one is a primary system and the
other is a backup. The problem is that different systems are sending data via ftp to the
primary. If the primary goes down, we haven't come up with a good way to continue recieving
data to the same IP address. Would this multiple IP address per card thing be a good solution?
