The registrant field says which blocks are the business arm and which are residential.
What it's used for
- A national carrier's business division. Thirty-four IPv4 prefixes and two IPv6 prefixes announced from Portugal, a hundred and fifty-five thousand addresses, across twenty-seven observed BGP neighbours.
Notable
- Most registrant entries end in a word for business, but one ends in a word for residential, so a block belonging to the consumer side is announced by the business network's number.
- Netnames carry two retired brands rather than the current one, each with an allocation date, and one of those dates uses a two-digit year where the rest use four.
- One block is registered to an unrelated party entirely, with a short code in place of a company name.
- The holder's name is written in capitals with the accents stripped out, so several words are missing the marks they normally carry.
- Eighteen addresses were queried for reverse DNS and two returned a name, both under a domain unrelated to the operator.
Interesting
- Business and residential arms sharing one AS number while keeping separate registrant labels is how a carrier splits its commercial reporting without splitting its routing.
- Thirty-four routes covering blocks from a
/17down to a/24is what a national network looks like after two decades of acquiring space in whatever sizes were available. - Two retired brands still naming the address space is the most durable kind of corporate history. The marketing changed twice and the registry did not.

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 1,773 prefixes, as published 2026-10-13. 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.
