AS30132 — ISC-F-AS

AS30132 announces 4 IPv4 prefixes covering 1,024 addresses and 2 IPv6 prefixes.

About this network

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.
