Summary

Portal Systems

United States of America · AI-generated

business managed-services datacenter

The AS handle PORTALSYSTEMS is held by Portal Systems, Inc.

What it's used for

  • The space carries business and data center infrastructure, evidenced by the netname PORTAL-SYSTEMS and the registrant Portal Systems, Inc.
  • The inventory consists of 1024 IPv4 addresses within a single prefix, 199.233.240.0/22, with 0 IPv6 prefixes announced.
  • With 1 observed neighbour, the low ratio of addresses to peers suggests a focused internal or managed service estate rather than a broad transit or access network.

Notable

  • The RDAP registrant Portal Systems, Inc. matches the AS holder, confirming consistent ownership of the address space.
  • The address inventory is compact and singular, consisting of one /22 block that aligns with the company's profile as a provider of custom network and cloud solutions in Northern Virginia.

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: 443 networks and 1,779 prefixes, as published 2026-10-24. 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.
