Summary

F5, Inc.

United States of America · AI-generated

business security infrastructure

F5-XC-FE is operated by F5, Inc.

What it's used for

  • The address space is registered under the netname F5SL-01 for all three prefixes, indicating internal corporate infrastructure rather than customer-facing access.
  • The AS announces 2048 IPv4 addresses across 3 prefixes with only 1 observed neighbour, a ratio consistent with a small, self-contained corporate estate rather than a transit or access provider.

Notable

  • All registrants for the announced prefixes are listed as F5, Inc., matching the AS holder.
  • F5, Inc. is a major provider of application delivery and security solutions, and this AS represents its internal network footprint.
  • The inventory consists of three contiguous IPv4 blocks within the 107.162.112.0/22 range, with no IPv6 prefixes announced.

Exchange presence is recorded rather than inferred: the directory collected by Packet Clearing House (https://www.pch.net/ixp/data) on 2026-10-16, 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: 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.
