My First Server's IP

As a freshman at MIT, I decided that it would be a fun way to get a head start on my CS classes by setting up a webserver and playing around with . As I learned later, a typical MIT Course 6 curriculum doesn’t care much for practical devops abilities (more on that subject for a later note), but I still remember the IP address that was first allocated to me for setting up my server at albertyw.mit.edu - 18.239.1.127.

I noticed recently that MIT sold off large portions of its 18.0.0.0/8 class A IP address range, which included the entire 18.239.0.0/16 range including my old IP address. I assume that the sold IP addresses will be made available randmoly as part of AWS’s Elastic IP Addresses pool for people to attach to AWS hosts and expose to the wider internet. While 18.239.1.127 still seems unallocated, I wish best of luck to whoever gets the IP address (unless I happen to grab it first).
