AS55163 LINKEDIN
Unclassified ARIN
Summary
business saas corporate
LINKEDIN is operated by LinkedIn Corporation.
What it's used for
- The address space carries corporate infrastructure, evidenced by reverse DNS entries such as
mail326.linkedin.comand108-174-2-128.fwd.linkedin.com. - The AS announces 768 IPv4 addresses across 2 prefixes and 1 IPv6 prefix, with only 1 observed neighbour, indicating a self-contained corporate network rather than a transit or access provider.
- Traffic from this AS consists of LinkedIn's own web services, API endpoints, and internal mail servers supporting its professional networking platform.
Notable
- Registrants for both announced prefixes are listed as LinkedIn Corporation, matching the AS holder.
- The address inventory is small and finely subdivided into two IPv4 blocks, consistent with an internal corporate estate segmented for specific service clusters.

Exchange presence is recorded rather than inferred: the directory collected by Packet Clearing House (https://www.pch.net/ixp/data) on 2026-10-27, licensed CC BY-NC-SA 3.0. Transit is inferred from observed BGP paths, never declared by either party.

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: 446 networks and 1,852 prefixes, as published 2026-10-27. 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.
