As of 10th November 2026, AS37705 (TOPNET), an access network registered in Tunisia with AFRINIC, originates 104 IPv4 prefixes covering 1.5M addresses and 32 IPv6 prefixes. By IPv4 address space that makes it the 362nd-largest of the 80,723 networks we see originating IPv4, and the 5th-largest of 24 in Tunisia. It is seen behind 3 upstream networks, most often AS5438 (Agence Tunisienne d'Internet) and AS327934 (SOCIETE NATIONALE DES…), and in front of 2 downstream networks. None of its announcements have a valid RPKI ROA. 98% of its routes reach at least 90% of full-feed peers.

Networks observed one and two hops upstream of AS37705 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.
