My original question was the fact of using 172.16.0.0/32 as a usable IP
address (not even caring about anycast).
Internal private network that is reachable by clients.
Hi Ryan, Clients meaning employee computers or clients meaning other networks who subscribe to your service and connect with a VPN? The the former, save yourself grief and use a different /32. For the latter, it's semi-clever. It neatly avoids the problem of customers using the same RFC1918 addresses as you. Even if they're using a subnet like 172.16.0.0/24, a /32 route can usually override that one address without ill effect. It's only semi-clever because the .0 address is a corner case in the code and corner cases are where bugs are most likely to happen. And if you're sending clients from that address to another host with a regular 172.16 address anyway... Regards, Bill Herrin

A single known ip address that redirects to the closest internal reposerver. 172.16.0.0/32 redirects to a usable subnet ip in 172.16.xx.xx by static route. Hi Ryan, Maybe if would help if you write the extended version because that's about as clear as mud. First you asked about routing. Now you imply HTTP.
