Summary

YRC Inc.

United States of America · AI-generated

logistics corporate business freight

The AS handle YELLOW-KCGO is held by YRC Inc., a major North American less-than-truckload freight carrier.

What it's used for

  • The address space carries corporate infrastructure for YRC Inc. and its subsidiaries, evidenced by netnames YRC-INC-NET and ROADWA-2 (Roadway Express, Inc.).
  • The AS announces 3328 IPv4 addresses across 9 prefixes with only 2 observed neighbours, a ratio indicating an internal corporate estate rather than a transit or access network.

Notable

  • Registrants align with the announcer, including YRC Inc. for the majority of prefixes and Roadway Express, Inc. for the 204.9.84.0/23 and 204.9.86.0/23 blocks.
  • YRC Inc. was formerly known as YRC Worldwide, Inc. (2006–2021) and Yellow Roadway Corporation (2003–2006), reflecting a history of rebranding within the logistics sector.
  • The inventory includes a prefix (68.23.21.0/24) with netname SBCIS-SIS80 and registrant AT&T Enterprises, LLC, which does not fit the primary YRC corporate profile.

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: 448 networks and 1,851 prefixes, as published 2026-10-29. 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.
