Enter Destination Address:  
Step 1: Convert all values to Binary:
a. IP Address:
b. Subnet Mask:
c. Destination Address:
Step 2: Apply Source subnet mask to Source address:
a. Address (from 1a):
Mask (from 1b):
= Src Network:
= Src Network:
Step 3: Apply Source subnet mask to Destination address:
Address (from 1c):
Mask (from 1b):
= Dst Network:
Step 4: Compare the network portions for equality:
Source: 
Destination: 
  Are they the same?
Result:    
 

This Subnet Calculator will take you through a step
by step calculation of a local or remote destination.
At the bottom you will see if the packet will be
sent to the local subnet, or the remote subnet.
