Unclassified APNIC
Summary
BorsodChem
enterprise business infrastructure
Four letters that end in a legal form the company stopped using, and the carrier holds both blocks.
What it's used for
- A chemical manufacturer's network. Two IPv4 prefixes announced from Hungary, no IPv6, seven hundred and sixty-eight addresses, through one observed BGP neighbour.
Notable
- The AS handle is four letters: two from the company name and two for the company form it had when the number was issued. The holder field ends in a different, newer form, so the label preserves a legal status the company has since changed.
- Both blocks carry that same four-letter string as their netname, with no country code, no date and nothing to distinguish one from the other.
- Neither block is registered to the manufacturer. Both list the national carrier's registry administrator and an abuse role, so the addresses belong to the provider and the number to the customer.
- The two blocks are adjacent, one twice the size of the other, cut from the same early range.
- Six addresses were queried for reverse DNS and none returned a name.
Interesting
- Legal forms change more often than networks do. A two-letter suffix baked into a handle is a timestamp: it says when the label was written, without any date being recorded anywhere.
- An industrial company with its own number, its provider's addresses and a single upstream has bought exactly one thing: the ability to keep announcing if it ever adds a second provider. Until then the number does nothing the addresses could 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: 453 networks and 1,848 prefixes, as published 2026-11-13. 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.
