About this network

AS-IMTA-BREST is operated by Institut Mines Telecom (IMT) Atlantique - Bretagne - Pays de la Loire.

What it's used for

• The address space carries institutional traffic for the Brest campus, evidenced by the netname ENST-BRETAGNE and reverse DNS entries like visio-d2-209.enst-bretagne.fr.
• The AS announces 1280 IPv4 addresses across 4 prefixes with only 2 observed neighbours, a ratio typical of a small, self-contained academic or research network rather than a transit provider.
• Traffic consists of staff, students, and research endpoints associated with the engineering school's campus infrastructure.

Notable

• All registrants for the announced prefixes are listed as INSTITUT MINES TELECOM; IMTA Abuse, which aligns directly with the AS holder.
• The address inventory is small and fragmented into four distinct blocks, including a /23 and three /24s, reflecting the specific allocation history of the ENST Bretagne campus.
