I have a Network with 10 Cisco 2950 switches and one 1700 Router and I ran out of internel Ip address. What I have done to give myself more addresses was I added a Secondary IP address on to my 1700 Router. The problem I have is that I can ping the other subnet by ip address but I can not ping any node by its name. I have also seen a slowdown in my networks performance. What can I do to resolve those two issues?
