That would be 8 addresses:192.132.206.160-167

 

by: rindiPosted on 2009-08-16 at 10:02:03ID: 25109517

No, you can't calculate the gateway address from that info.

Should I assume .160 is the gateway address?

 

by: wiscomPosted on 2009-08-16 at 10:02:46ID: 25109521

Hi,

So most of the time it is tfirst IP address. in this case 192.132.206.161

A/

 

by: jrfaustPosted on 2009-08-16 at 10:04:43ID: 25109528

Your host address range is 192.132.206.161 - 166.  Since your public IP address is 192.132.206.162, your gateway is probably 192.132.206.161.

You have a block of 8 addresses
the first & last are reserved so assuming 161 is the gateway would make sense
if you run tracert to an Internet address you will know for sure
