"..for some blocks I've taken over admin for." Make sure you are visibly listed as a Point of Contact on those records in the appropriate RIR, so that folks who get your request can verify you. Even better, register in your RIR's RPKI program and generate a ROA for it. Info about ARIN's here: https://www.arin.net/resources/rpki/index.html Then yes, notify their upstreams/peers if needed and post here if things get really desperate - have your records in order first. --Heather -----Original Message----- From: Jim Mercer [mailto:jim@reptiles.org] Sent: Monday, November 12, 2012 2:44 PM To: nanog@nanog.org Subject: "authority" to route? Hi, Is there a common practice of providers to vet / validate requests to advertise blocks? Who is the "authority" when it comes to determining if a request for routing is valid? Is it the WHOIS data maintained by the various RIR? It seems I'm playing whack-a-mole to get some routes shut down for some blocks I've taken over admin for. If I email the contacts for the AS in WHOIS, and get no response, or a negative response, should I start going to their peers? Some practical advice would be appreciated. -- Jim Mercer Reptilian Research jim@reptiles.org +1 416 410-5633 "He who dies with the most toys is nonetheless dead"
