Here's a small sample. If the IP addresses, etc. are not Nemeth, would I use the Nemeth punctuation indicator prior to the "dot" in the equation?
Convert the answer back into decimal:
11000000.10101000.01100100.01110000 = 192.168.100.112
The IP address 22.214.171.124 belongs to the 192.168.100.112 network when a mask of 255.255.255.240 is used.
