Summary

Republic Airways Holdings

United States of America · AI-generated

airline corporate business

The AS handle REPUBLIC-AIRWAYS-PRIMARY is held by Republic Airways Holdings, Inc.

What it's used for

  • The address space carries corporate infrastructure, evidenced by the netname EXPEDIENT-17 associated with the registrant Expedient.
  • The AS announces 256 IPv4 addresses across 1 prefix and maintains 2 observed neighbours, indicating a small, self-contained corporate network rather than a transit or access provider.
  • Traffic from this AS consists of internal corporate systems and office workers for the airline holding company, which operates regional airlines such as Mesa Airlines and Republic Airways.

Notable

  • The RDAP registrant for the announced prefix is Expedient, which differs from the AS holder Republic Airways Holdings, Inc., suggesting the address space is leased or managed by a third-party provider.
  • The inventory consists of a single /24 block (209.143.74.0/24) with no IPv6 prefixes, representing a minimal footprint typical of a specific corporate site or data center connection.

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: 442 networks and 1,782 prefixes, as published 2026-10-16. 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.
