Chicago Equinix IX LAN oddity

[JASON BOTHE via NANOG <nanog () nanog org>]

Hi all

I realize this might not be the right list but I have a request to peer on the Chicago Equinix IX to a 206.223.119 IP 
but we and many others are on the 208.115.137 network. While I await a response from the peering partner, I’d curious 
to know if this is an error, perhaps there was a renumber at one time or I’m flat out just missing something. 

Cheers!
