Summary

Dalko, LLC

United States of America · AI-generated

business logistics corporate

The AS handle DALKO-NETWORKS is held by Dalko, LLC.

What it's used for

  • The address space carries corporate infrastructure for a freight and logistics provider, as indicated by the netname DALKO-CGNT-NET-1 and the registrant DALKO NETWORKS.
  • The network announces 1024 IPv4 addresses within a single prefix (38.158.240.0/22) and maintains only 1 observed neighbour, a ratio consistent with an internal corporate estate rather than a transit or access provider.

Notable

  • The RDAP registrant DALKO NETWORKS aligns with the AS holder Dalko, LLC, confirming the space is owned by the operator.
  • Dalko, LLC operates as DALKO Resources, a logistics and supply chain company with over 75 years of experience in freight transportation and warehousing.
  • The inventory consists of a single contiguous /22 block with no IPv6 prefixes, reflecting a compact, dedicated corporate address space.

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: 443 networks and 1,784 prefixes, as published 2026-10-19. 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.
