Jim’s not a happy camper, and wants to know why ARIN disassociated him
with his address block randomly sometime after 2010. Jim says that he’s
been been using the address block for his house since leaving Sprockets

Now on to the more dangerous variation of this story - it starts the same, sounds

although it could be argued that it excessively impacts legacy address holders
(those who have not been updating their IP address records over time.)
