Unclassified ARIN
Summary
Userworld
isp hosting business
The last number in this range, and the smallest network in it.
What it's used for
- A small provider's network. 512 addresses in a single IPv4 prefix, with one observed BGP neighbour and no IPv6 announced.
Notable
- The whole footprint is
199.27.148.0/23, half the size of almost every other network in this range. - The netname is
USERWORLD, matching the AS handle and the registrant exactly. - The registrant differs from the AS name only in where the full stop falls after the company suffix.
- Three addresses were queried for reverse DNS and none returned a name.
Interesting
- 512 addresses with one upstream is the minimum arrangement that justifies holding an AS number at all. Below this there is no reason not to take addresses from a provider and skip the paperwork entirely, which is what nearly everyone does.
- Every field agreeing is the mark of a record filed once, by the person who runs the network, and never handed to a carrier's provisioning system to be rewritten. Most of the inconsistencies catalogued across this range come from that handover.
- The company name reads as a product from the era when getting people online was itself the product. It has been announcing continuously since the routing archives begin, which makes it one of the longest-lived small networks here.
- No IPv6 and a single carrier is a network that works and has not been asked to do anything else.

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: 451 networks and 1,853 prefixes, as published 2026-11-04. 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.
