I create this tool for you to easily calculate equivalent Wildcard Mask for any given IPv4 address and subnet mask.
You can make use of this tool when you have to configure Cisco IOS Access Control List, "network" command in routing protocols, and you can also do a quick double-check about whether the wildcard mask is matching the designated subnets or not.
In fact, this tool is revised from another tool I have posted before.

Here I just want to point out one aspect to make you feel better about vPC.
