As of 10th November 2026, AS1031 (PEER 1031 LLC), a transit carrier registered in the United States with ARIN, originates 1 IPv4 prefix covering 256 addresses and 3 IPv6 prefixes. By IPv4 address space that makes it the 59,958th-largest of the 80,723 networks we see originating IPv4, and the 13,081st-largest of 18,750 in the United States. It is seen behind 53 upstream networks, most often AS6453 (TATA Communications (America) Inc) and AS39122 (Blacknight Internet Solutions Limited), and in front of 277 downstream networks. None of its announcements have a valid RPKI ROA; 1 is RPKI-invalid. 0% of its routes reach at least 90% of full-feed peers, and 3 prefixes are also originated by another network.

Networks observed one and two hops upstream of AS1031 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.
