Summary

Delcom

United States of America · AI-generated

residential business education

DELCOM-ASN is operated by Delcom, Inc.

What it's used for

  • The address space carries residential DSL and static IP services, evidenced by reverse DNS entries such as dsl-76-77-24-128.dellcity.com and static-76-77-25-126.networklubbock.net.
  • Netnames like DELCO-V4-00 through DELCO-V4-03 and FWL-IPV4 indicate internal segmentation of the corporate estate, while REGION-18-EDUCATION-SERVICE-CENTER---TEXAS points to an education sector allocation.
  • With 5,376 IPv4 addresses announced across 8 prefixes and only 2 observed neighbours, the ratio suggests an access or eyeball network rather than a transit provider.

Notable

  • Registrants for the majority of prefixes are Delcom, Inc., matching the AS holder, though 76.77.24.0/23 is registered to WWLTH, Inc and 69.94.187.0/24 to Region 18 Education Service Center.
  • The inventory includes a single IPv6 prefix, 2606:edc0::/32, alongside the IPv4 blocks.
  • The address inventory is finely subdivided into multiple /22 and /24 blocks, consistent with site-by-site segmentation for a regional operator.

Exchange presence is recorded rather than inferred: the directory collected by Packet Clearing House (https://www.pch.net/ixp/data) on 2026-10-16, licensed CC BY-NC-SA 3.0. Transit is inferred from observed BGP paths, never declared by either party.

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 1,783 prefixes, as published 2026-10-17. 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.
