Thank you for that very informative post, I assumed as much but I still wanted to see if there was someone out there that could give me some more infromation, which you did, unfortunately it was the same conclusion... Smile

Yes, it's just a md5 IP, so that cracks in under a second with hashcat.

Well, for what it's worth, here are the X-Trace headers from my last individual posts:

individual.net OeIYWJPyf5rdp0IlMHyBPAFnfp+RA412tm285iqgU5R6GiiRk=
individual.net LOkweuyhAZuVtYh9sAtC5AJeEIgSU2RT25gUNxzG0xx1ze9j0=

individual.net 4TPo539ILKqS7CsJ8U5xsAweUszdWqVRh58abc8milnuIX2ko=

If the IP is in there, it's the same for all of these.
