Summary

SocketLabs

United States of America · AI-generated

email business infrastructure

The AS handle SOCKETLABS is held by SocketLabs.

What it's used for

  • The address space carries email delivery infrastructure, evidenced by reverse DNS entries such as s1-b500.socketlabs.email-od.com and the netname SOCKET-1.
  • The AS announces 1024 IPv4 addresses across 1 prefix with 1 observed neighbour, indicating a dedicated infrastructure network rather than a transit or access provider.
  • Traffic from this AS consists of outbound email delivery services for marketing, transactional, and smart-hosted email applications.

Notable

  • The registrant SocketLabs matches the AS holder and the netname SOCKET-1 for the announced prefix.
  • The address inventory consists of a single /22 block (142.0.180.0/22), which is finely subdivided for internal use.

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 1,779 prefixes, as published 2026-10-23. 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.
