As of 11th November 2026, AS11042 (NETWORK TRANSIT HOLDINGS LLC), an access network registered in the United States with ARIN, originates 97 IPv4 prefixes covering 66.8k addresses and 6 IPv6 prefixes. By IPv4 address space that makes it the 3,393rd-largest of the 80,747 networks we see originating IPv4, and the 1,148th-largest of 18,752 in the United States. It is seen behind 3 upstream networks, most often AS174 (Cogent Communications, LLC) and AS46887 (Zayo (fka. Crown Castle)), and in front of 4 downstream networks. 2% of its announcements have a valid RPKI ROA; 1 is RPKI-invalid. Over 99% of its routes reach at least 90% of full-feed peers, and 1 prefix is also originated by another network.

Networks observed one and two hops upstream of AS11042 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.
