Summary

PFSweb

United States · AI-generated

business enterprise hosting

The same company registered as two spellings, one with a space and one without.

What it's used for

  • An e-commerce fulfilment company's network. 1,024 addresses across two IPv4 prefixes, three observed BGP neighbours, and no IPv6 announced.

Notable

  • 12.18.76.0/23 is netname ATT-NET-12-18-76-0-23, registered to PFSWEB in capitals.
  • 192.157.74.0/23 is netname PFSWEB-NETWORK, registered to PFS Web with a space.
  • The AS handle recorded in inventory reads AS13471 - PFS Web, the number and the name together.
  • Six addresses were queried for reverse DNS and none returned a name.

Interesting

  • One organisation, two registry records, two spellings of the name. Anyone matching networks to companies by string comparison gets two companies here, which is how a single business ends up counted twice in datasets built that way.
  • The carrier block's netname is the address written out with the prefix length on the end, generated rather than chosen. The other was typed by somebody who added -NETWORK because a netname wants a noun.
  • A handle containing the AS number itself is a record created by a tool that had the number and the name and joined them, rather than by a person picking a short label.

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 1,783 prefixes, as published 2026-10-17. 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.
