title: How to convert IPv4 address to decimal
body: <p>Is there a function to convert an IPv4 address in dotted decimal notation (e.g., "192.168.0.1") into a decimal value?</p>
  
  <p>There are several questions similar to this, but all are looking for or have answers that involve writing a function to solve the answer.  I'm looking for an existing function in a library.</p>
