The netname calls the block the original one, which only makes sense if a second was expected.
What it's used for
- A provider's network. Two prefixes announced from the United States, one of them IPv6, two hundred and fifty-six IPv4 addresses, through one observed BGP neighbour.
Notable
- The netname is the company name, then the word for something that came first, then three characters naming the protocol version with the letter for the version dropped.
- That protocol label is unnecessary. Every block in this part of the registry is that version, and the company's other prefix is the other version and is not in the registry sample at all.
- The AS handle is the company name alone, and the holder field is that handle plus the legal form.
- The company is the only entry on the block. There is no abuse role and no technical contact.
- The IPv4 prefix is the smallest routable size and it is the whole holding in that version.
- Three addresses were queried for reverse DNS and none returned a name.
Interesting
- Calling something the original implies a successor. The word was written by somebody who already knew a second block was coming, or who was labelling this one after the second had arrived. Either way the netname records a plan rather than a fact.
- One small block, one upstream, no reverse names and no contacts other than the company: a provider at the size where the network is one person's responsibility and the paperwork is done once.

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.
