Germany · AI-generated

business germany small

PORTA-AS is the autonomous system handle for BIOS Technologie-Partner GmbH.

What it's used for

  • The address space carries corporate infrastructure, evidenced by the netname HS-PORTA-PISPACE and registrants including BIOS Technologie-Partner GmbH and Message Solution.
  • The AS announces 512 IPv4 addresses and 1 IPv6 prefix, with only 1 observed neighbour, indicating a small, isolated internal network rather than a transit or access provider.
  • Traffic from this AS consists of internal corporate communications and services for the technology partner organization.

Notable

  • Registrants align with the announcer, listing BIOS Technologie-Partner GmbH alongside administrative roles for Message Solution.
  • The inventory consists of a single /23 IPv4 block and one /48 IPv6 prefix, representing a compact, self-contained corporate estate.

Reputation

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: 440 networks and 1,773 prefixes, as published 2026-10-13. 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.
