Load balancing, setting up 2 IP addresses for the same website...

[Umar Pirzada]

Hi

i was just wondering how www.yahoo.com gives 7-8 IP addresses on a
nslookup query? This does mean that they have some sort of load
balancing implemented. If a query for www.yahoo.com is from asia it
goes to another server, if from europe it goes to another....

How do they do this? I have a website hosted and i want to do
something of the same sort. For a start i want to set up my server to
give services from 2 subnets....i mean to say that i have radio
connectivity with 2 ISPs. At the moment i have a primary LINK and a
backup link. what i want to do is utilize both the links at the same
time and create a load balancing scenario. I hope i am making my point
clear. I want to set up two LAN cards with differnt IP addresses from
the 2 ISPs and then somehow create the situation where both are active
at both times.

What do i do? Plz guide...

Thanx...
