Summary

Internet Systems Consortium

United States of America · AI-generated

infrastructure vpn non-profit dns

The AS handle ISC-F-AS is held by Internet Systems Consortium, Inc.

What it's used for

  • The address space carries internal infrastructure and VPN endpoints, evidenced by reverse DNS entries such as vpn-eu-client-64.isc.org and tunnel.ams1.isc.org.
  • The AS announces 1024 IPv4 addresses across 4 prefixes and 2 IPv6 prefixes, while maintaining 101 observed neighbours; this ratio of small address inventory to high peering count indicates a transit or infrastructure role rather than an access network.

Notable

  • All registrants for the announced prefixes are listed as Internet Systems Consortium, Inc., with netnames ISC-NET3 and ISC-NET6, fully agreeing with the AS holder.
  • The address inventory consists of four distinct /24 blocks in the 149.20.0.0/16 and 199.6.0.0/16 ranges, representing a finely subdivided internal corporate estate.

Exchange presence is recorded rather than inferred: the directory collected by Packet Clearing House (https://www.pch.net/ixp/data) on 2026-10-20, 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 1,778 prefixes, as published 2026-10-20. 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.
