Summary

Screaming Net

United Kingdom · AI-generated

enterprise business

One person, one /24, one IPv6 /48, and an AS number — the smallest complete independent network there is.

What it's used for

  • Independent connectivity from London. 256 addresses in a single IPv4 prefix and one IPv6 prefix.

Notable

  • The IPv4 block is 194.153.117.0/24, netname BJEONYX-PI, registered to a named individual, Jaco Engelbrecht.
  • The IPv6 announcement is 2001:67c:2738::/48, out of the registry's own assignment range.
  • The AS handle is SCREAMING-NET-AS London.
  • Three sampled addresses were queried and none returned a name.

Interesting

  • PI in the netname stands for provider independent, and both blocks here are exactly that: addresses that belong to the holder rather than to whoever currently carries the traffic. Together with an AS number, they are the complete set of things needed to be a first-class participant in Internet routing rather than a customer of one.
  • This is the fourth block in this stretch of the number range registered to a person rather than a company. The registry makes no distinction, and neither does BGP: an individual with a /24, a /48 and a number is indistinguishable at the protocol level from a corporation.
  • The economics have changed underneath this arrangement. A /24 now costs real money and a registry /48 requires an annual fee, so a holding assembled when both were cheap is worth considerably more than it cost.

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: 436 networks and 1,769 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.
