Use "Unassigned" or IP address for IIS?

I am wondering when I am creating a new website should I choose an ip address from the list or leave it "unassigned ip address"?

Thanks

Solution 1:

Typically you would leave it unassigned unless any of the following (as examples):

1) You have multiple SSL Sites that do not support SNI (like vhosts for SSL), so you must map an SSL and IP to the site's FQDN.

2) You have multiple networks interfaces and do not want to listen on all interfaces and all IPs.

3) Your site is behind a local proxy, and you want to prevent bypassing the load balancer (also recommend non-standard ports if doing this method or dedicated load balancer), common for tomcat or nodejs.
