Tyler Schultz, Alvaro Perez Shirley, and Brian Cunnie created sslip.io on Tuesday August 11, 2015 during a Pivotal Software-sponsored Hack Day. Thanks Pivotal!
-Sam Stephenson built xip.io, upon which much of our code is based. He also suggested the name sslip.io. Thanks Sam!
-Justin Smith advised us on the security implications of releasing an SSL certificate and key to the general public. Thanks Justin!

Can you make the hostnames easier to remember? I'm being force to memorize IP addresses.
Unfortunately, no. We appreciate that "52-0-56-137.sslip.io" is not an easy-to-remember hostname, whereas something along the lines of
