Summary

One netname is a protocol, and one block belongs to an individual renting addresses out.
What it's used for
- A business services provider. Four IPv4 prefixes announced from Kazakhstan, no IPv6, one thousand two hundred and eighty addresses, through a single observed BGP neighbour.
Notable
- One block's netname is the name of a voice-over-network protocol, written in mixed case, rather than anything identifying a holder.
- Another is the bare company abbreviation, and both list an operations centre as their only contact, with the company's name spelled in the singular where the holder string has it plural.
- A third block is registered to a private individual trading under a business name whose subject is the renting out of addresses.
- The AS handle appends the country to the abbreviation, which the country field already carries.
- One block's registry lookup failed, so its details are unknown rather than absent.
- Twelve addresses were queried for reverse DNS and none returned a name.
Interesting
- A protocol name in a netname is a network that filled the field with what the block is for rather than whose it is. It reads as documentation right up until the block is repurposed.
- Address rental turns up twice in this stretch of numbers, once as a company whose netnames say marketplace and once here as a sole trader. The market is old enough to have both shapes in it.
- One thousand addresses behind one upstream, with four blocks from two unrelated ranges, is a network assembled piece by piece from whatever was available.

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: 443 networks and 1,779 prefixes, as published 2026-10-24. 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.
