Change from Class C to Class B!
Posted on 2007-11-13
I have 4 sites for my company in different locations, each of the sites is configured as different subnet (for example site 1 is 100.100.100.0, site 2 is 100.100.101.0
...etc). Now I have a device that is connected to the network in one of the sites (this device is PBX VOIP), when I try to ping this device from any site it gives me requested time out, however if I ping it from his own network it works! but if I ping any other device from any other site/network it works fine!
It seems to me that I need to upgrade the subnet mask on the networks to be 255.255.0.0, is that a good solution? What are the impact of such action?
