AS28330

RegistryLACNIC

As of 11th November 2026, AS28330, a network registered with LACNIC, originates 30 IPv4 prefixes covering 24.6k addresses and 8 IPv6 prefixes. By IPv4 address space that makes it the 6,383rd-largest of the 80,743 networks we see originating IPv4. It is seen behind 1 upstream network, most often AS22381 (SAMM (Megatelecom)). Every one of its announcements has a valid RPKI ROA, and none are RPKI-invalid. 100% of its routes reach at least 90% of full-feed peers.

Networks observed one and two hops upstream of AS28330 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.
