Usually each of your PCs will register their hostname with the DHCP server when they ask it for an IP. Your modem/router will probably have a web page (look for status or somesuch) that will reveal the names, IP address and MAC (ethernet) address it knows about. Often they also act as a DNS and as such will also reveal the name to IP address mapping via DNS. You can query this with the command "nslookup <hostname> <router_ip>.
A lot of these router/modems even support WINS (the "old" Windows dynamic name service), you can query this with "nmblookup -U <router_ip> -R <hostname>". BTW Almost certainly the IP allocated is not associated with the physical port. Usually allocation is simply out of the next one available in the pool of addresses for DHCP.
