3 public IP's on a 2621 routers

[CSCO10881970]

Our ISP has given us 3 public IP's and im planning to use it all on our 2621 router as a single connection, could it be possible for me to implement this so as to maximize the 3 IP's given to us?

3 blocks of IPs or 3 consecutive IPs falling under a single block ? Whats the subnet mask ? Have you already been assigned a /30 (or similar) subnet for the wan link ?

Yes, we are using 3 consecutive IPs falling under a single block, could I combine this under the single router?

Hi,

Please let me know what are the IP subnets with subnet mask.What type of connectivity you have with ISP? Two IPs are required for WAN connectivity.For that you need one /30 (2 usable IPs) IP subnet.For LAN also you need atleast one IP.

If you have 3 consecutive IPs falling in a single block then you will not be able to use them on a single router.
