Unclassified APNIC
Summary
AT&T Global Network Services Nederland B.V.
business corporate enterprise netherlands
The AS handle OPENNET-SA is held by AT&T Global Network Services Nederland B.V.
What it's used for
- The address space carries corporate infrastructure for HP Inc., as evidenced by the netname
HP-INTERNETassigned to all major prefixes. - The AS announces 14848 IPv4 addresses across 15 prefixes and 1 IPv6 prefix, while maintaining only 2 observed neighbours, indicating a dedicated internal corporate estate rather than a transit or access network.
Notable
- Registrants for the largest prefixes are consistently listed as HP Inc., which differs from the current AS holder, AT&T Global Network Services Nederland B.V.
- The address inventory is finely subdivided into multiple /20, /21, /22, /23, and /24 blocks, reflecting site-by-site segmentation typical of a large enterprise network.

Internet exchanges
No exchange port on file. Many exchanges publish no participant list, so this is not proof of absence.
Exchange presence is recorded rather than inferred: the directory collected by Packet Clearing House (https://www.pch.net/ixp/data) on 2026-10-31, 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: 447 networks and 1,843 prefixes, as published 2026-11-01. 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.
