Policy Statement on Address Space Allocations

Worse yet, I applied for several class-C's for companies years ago (before
the CIDR stuff really got off the ground) that I _know_ are obsolete, but
the Internic won't let me recycle them. I should have left my name on them
in some way I guess. The problem is, the address listed is obsolete, the
phones disconnected and in one case the contact is dead! So, how is one
supposed to try and recycle in this sort of situation?

  Let me know which ones they are, and I'll ensure they
  get taken care of.
