Two blocks carry the same carrier-plus-company netname, and one of them has a letter wrong.

What it's used for

  • A regional provider's network. Ten prefixes announced from the United States, one of them IPv6, six thousand six hundred and fifty-six addresses, through seven observed BGP neighbours.

Notable

  • Six blocks carry the company's name alone as their netname, with no country code, no date and no numeral to distinguish them.
  • Two more pair a carrier's four-letter abbreviation with a four-letter cut of the company name. The two abbreviations of that carrier differ by one letter, so one of the pair is misspelled and both have stayed that way.
  • A ninth block is named after a different company with a year appended, and is registered to that company rather than to the holder.
  • Twelve of eighteen queried addresses answered. Eleven use the address hyphenated into four parts, the word for a static assignment, and a domain built from the brand plus the word for fibre.
  • The twelfth is a city name on the brand's shorter domain, so one router in the sample is named for where it sits rather than for the address it answers on.
  • Several answers are block boundaries and resolve like everything else.

Interesting

  • A one-letter difference between two otherwise identical netnames is invisible until someone searches for one and finds half the blocks. Nothing in the registry cross-checks them, so the typo is permanent.
  • The one hand-named router among a dozen generated names is where the network stops being a spreadsheet and starts being a building.

Classification and threat

Unclassified Not in the curated lists. Most of the ~80,000 allocated ASNs are not.

Spamhaus DROP

Not on ASN-DROP The network as a whole is not listed.

No DROP prefixes None of its announced space is on the DROP prefix list.

Spamhaus DROP ("Don't Route Or Peer") lists space and networks run by, or hijacked for, spam and cybercrime operations: 442 networks and 1,784 prefixes, as published 2026-10-19. A short, high-confidence list, so a match is worth taking seriously, and absence from it says little on its own.

FBI IC3

No IC3 indicators Nothing from the FBI IC3 feed.

IC3 threat data is alpha. Absence of an indicator is not evidence of good behaviour, only of absence from this one feed.
