AS7974 Instituto Mexicano del Petroleo

AS7974 belongs to the Instituto Mexicano del Petróleo (IMP), Mexico's public

petroleum research institute — a state research centre supporting the national oil

industry, headquartered in Mexico City.

What it's used for

• The institute's own network: research computing, laboratories, engineering and administration.
• IMP's public services. rDNS in the space resolves under imp.mx (for example briseida.imp.mx), confirming the holder directly.

Notable

• This is a government research institution, not a company and not an energy operator. It is a public research centre under Mexico's energy administration, so its address space is institutional: an IP here is an IMP workstation, lab machine or server.
• The AS is small — three /24s, about 768 addresses, split between legacy 192.100.180.0/24 and 192.100.181.0/24 and a LACNIC-era 200.33.186.0/24. Size here tracks the institute, not the AS number.

Interesting

• The 192.100.180.0/24 and 192.100.181.0/24 pair are pre-CIDR "Class C" style assignments, which places IMP among the earlier Mexican organisations to hold routable address space of its own.
