I haven't yet received a response from CableVision's listed ARIN contact, but I've got Tata Communications via ip-addr@tatacommunications.com and I'll be emailing swipper@verizon.net for Verizon a little later today. Thanks for the off-list replies, this thread should be resolved. On Tue, Sep 24, 2019 at 9:40 AM Chip Parker <infowolfe@gmail.com> wrote:

Does anybody have any contacts for IP assignment/reassignment with: TATA CableVision MCI dba Verizon

I'm looking to talk to someone at each of the above companies about some reassignments that I've inherited from a company that the company I work for purchased a few years ago.

TL;DR trying to "fix" reassignments in ARIN, but can't without contact with the above companies. Trying to find a contact that'll speak to me about fixing these reassignments.
