About this network

Eighteen prefixes carved out of one range, every one labelled with the range instead of itself.

What it's used for

• A banking group's network. Eighteen IPv4 prefixes announced from Mexico, no IPv6, and six observed BGP neighbours.

Notable

• All eighteen prefixes fall inside 148.244, split into pieces from a /20 down to individual /24 blocks.
• Every resolved block carries the same netname, and that netname is not a name at all: it is the first and last address of the parent range written out and joined with a hyphen.
• The registrant is the bank under a shorter trading name than the holder record uses, with its corporate form missing its final punctuation.
• Six of eighteen sampled addresses answered, all in the form static-148-244-11-254.alestra.net.mx, under a carrier's domain rather than the bank's.
• The AS handle is the full company name with spaces in it, which most holders in this range replace with a short code.

Interesting

• Splitting one range into eighteen announcements is real routing work, and the registry records none of it. Each piece points back at the whole, so the registry cannot say which part of the bank holds which addresses, only that the bank holds all of them.
• Address-range netnames turn up on unrelated holders elsewhere in this corpus. They are what a registry produces when nobody supplies a name, and they read as data rather than as a label.
