Neighbors are networks seen next to AS3257 in AS paths collected by RIPE RIS. Provider, peer and customer relationships come from CAIDA’s AS relationship data (November 2026). A provider sells transit to this network, a customer buys transit from it, and peers exchange their own and their customers’ traffic. Unknown means CAIDA has no record of the pair yet. “Paths seen” counts the paths in which the two networks are adjacent.
