I need to share 1 IP address with several pools

I would like to be able to share a single IP address with a number of different sites and different pools. We are trying to replace an appliance that does this today. It allow the dns entries to all point to 1.1.1.1 and then based on the URL - xx.domain.com or yy.domain.com or zz.domain.com send the request to the appropriate pool - xx, yy or zz.

 

 

Has anyone done this?
