As of 11th November 2026, AS6614 (T-Mobile USA, Inc.), an access network registered in the United States with ARIN, originates 55 IPv4 prefixes covering 551k addresses. By IPv4 address space that makes it the 683rd-largest of the 80,747 networks we see originating IPv4, and the 165th-largest of 18,752 in the United States. It is seen behind 11 upstream networks, most often AS3356 (Lumen (Level 3)) and AS2914 (NTT America, Inc.), and in front of 1 downstream network. None of its announcements have a valid RPKI ROA. 96% of its routes reach at least 90% of full-feed peers, and 2 prefixes are also originated by another network.

Networks observed one and two hops upstream of AS6614 in real AS paths. A thicker line means more vantage points saw that adjacency, so weight tracks how well attested it is — not how much traffic it carries. Adjacency is an observation; whether it is a transit purchase or a settlement-free peering is an inference, and is labelled as one wherever we show it.
