My company is in the process of setting up co-location to host production servers. the hosting location assigned 2 IPs for us. the first one is VLAN Uplink, 64.209.230.248/30. the other one is
64.209.230.248/25 and that for colocation behind firewall. the colocation consist of router, firewall, 2web servers, 1 mail server and a SQL server. now I am not sure how that is going to work. is the uplink IP is going to be assigned to the router and what the subnet will be exactly and how do I subnet the other IP. thank you

Hi.

The first subnet 64.209.230.248/30 , gives you two addresses 64.209.230.249 and 64.209.230.250 ,your ISP will use on off them in his end probably ...249 and you should assign the other to the wan interface on your router.

You have probablywritten a wrong second ip range,since it is the same as your wan range!!
But the general idea of an /25 net is that you have
126 addresses to your disposal, : EG 10.10.10.0/25
means that you have the addresses from 10.10.10.1 to 10.10.10.126 to you disposal, 10.10.10.127 is your broadcast address.

Your subnet mask is 255.255.255.128 on a /25 net.

You should assign the first IP to you lan interface on your router and develop a IP-plan for the rest of the ip?s.
Remember that the ip on your router (LAN interface) is your default gateway.
