Summary

Walbridge Aldinger Company

United States of America · AI-generated

business construction corporate enterprise

WALBRIDGE-ALDINGER-CO-DTW is the autonomous system for Walbridge Aldinger Company.

What it's used for

  • The address space carries corporate infrastructure for a major construction management firm, as indicated by the netname WALBRIDGE-0000335-55-0 and registrant Walbridge Aldinger Company.
  • The AS announces 256 IPv4 addresses across 1 prefix (35.128.55.0/24) with 2 observed neighbours, a ratio consistent with a small internal corporate estate rather than a transit or access provider.

Notable

  • The RDAP registrant Walbridge Aldinger Company matches the AS holder, confirming direct ownership of the announced space.
  • The address inventory consists of a single /24 block, representing a compact, self-contained network footprint typical of a large enterprise managing its own connectivity.

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: 452 networks and 1,853 prefixes, as published 2026-11-05. 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.
