AS15954 TECNOCRATICA Tecnocratica Centro de Datos, S.L.

Four contacts on every block: the company, an administrator, an operations centre and an abuse role.

What it's used for

• A data centre operator's network. Thirteen IPv4 prefixes and three IPv6 /32s announced from Spain, fourteen thousand three hundred and thirty-six addresses, across forty-nine observed BGP neighbours.

Notable

• Nine blocks share one template: a country code, the brand, and a date, with the same four contacts listed in the same order every time.
• Two of the remaining blocks belong to other companies outright, one an information services firm and one whose registered name spells out technical assistance for computing and communications in full.
• A third carries a different brand entirely, with the word for clouds and a digit, and the operator's own contacts but not its name.
• That same second brand appears again as the domain of the one answering address, whose host label packs a machine number, a letter, a rack number and a position into a single string.
• Two of the three IPv6 /32s are adjacent ranges allocated separately rather than as one.

Interesting

• Listing an administrator, an operations centre and an abuse role separately is how a hosting company answers three different kinds of mail without any of them reaching the same inbox. Most networks in this range manage one contact; this one keeps all three current across thirteen blocks.
• A second brand in the reverse names and a third in the netnames is the ordinary residue of buying smaller hosts and never renumbering them.
