Summary

Jeppesen ForeFlight

United States of America · AI-generated

business aviation corporate

The AS handle JEPPESEN is held by Jeppesen ForeFlight Inc.

What it's used for

  • The address space is registered under the netname JEPPFF for Jeppesen ForeFlight Inc., indicating a corporate network for the aviation charting and flight planning company.
  • The AS announces 3328 IPv4 addresses across 8 prefixes with 4 observed neighbours, a ratio consistent with an internal corporate estate rather than a transit or access provider.

Notable

  • All registrants in the RDAP data align with the announcer, listing Jeppesen ForeFlight Inc. and Jeppesen ARIN Admin for every prefix.
  • The address inventory consists of eight distinct IPv4 blocks within the 169.143.0.0/16 range, showing fine-grained subdivision typical of site-by-site corporate segmentation.

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: 446 networks and 1,852 prefixes, as published 2026-10-27. 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.
