Summary

United States of America · AI-generated

education research transit

AS-PENGUIN is operated by Penguin Networks.

What it's used for

  • The address space is registered under netnames PENGUIN-IPV4-410-0 and PENGUIN-IPV4-0, both attributed to Penguin Networks.
  • The AS announces 512 IPv4 addresses across 2 prefixes and 4 IPv6 prefixes, while maintaining 10 observed neighbours.
  • This ratio of limited address inventory to a moderate number of peering partners indicates a transit or research network role rather than a large-scale access provider.

Notable

  • Registrants for both announced IPv4 prefixes match the AS holder, Penguin Networks.
  • The address inventory consists of two distinct /24 blocks and four IPv6 prefixes, indicating a compact and specific allocation.

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: 431 networks and 1,775 prefixes, as published 2026-10-11. 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.
