Whats the best way to get in contact with Level3 to make an IRR change... if your not a Level3 customer?

I tried emailing rr@level3.net but that bounces back as an unmonitored mailbox. There are dup IRR entries in Level3's db for my prefixes (legacy from a carrier I used over 10 years ago). My prefixes are in Arin's IRR and I would like that to be the only source.

In Mar 2018 I had success sending such clean-up requests to the technical contact address in the AS3561 whois record. The address has changed since then, but maybe whoever gets that email is still interested in maintaining their IRR. ________________________________________________________________________ Jay Ford, Network Engineering Group, Information Technology Services University of Iowa, Iowa City, IA 52242 email: jay-ford@uiowa.edu, phone: 319-335-5555
