Summary
Prairie Grove Telephone Co.
residential dsl rural telecom
The AS handle PGTC-COM is operated by Prairie Grove Telephone Co.
What it's used for
- The address space carries residential DSL access, evidenced by reverse DNS entries such as
d6142.dsl.pgtc.comandc1790.dsl.pgtc.com. - The network announces 12,288 IPv4 addresses across 2 prefixes (74.51.64.0/19 and 69.4.192.0/20) with only 2 observed neighbours, a ratio characteristic of a local access provider rather than a transit carrier.
Notable
- Both RDAP registrants match the announcer, identified as "Prairie Grove Telephone Co.; Admin" for the netnames PGRV-NET2 and PRAIRIE-GROVE-TELEPHONE-CO.
- The inventory consists of two distinct IPv4 blocks with no announced IPv6 prefixes, reflecting a traditional rural telephone company infrastructure.

Internet exchanges
No exchange port on file. Many exchanges publish no participant list, so this is not proof of absence.
Exchange presence is recorded rather than inferred: the directory collected by Packet Clearing House (https://www.pch.net/ixp/data) on 2026-11-04, 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: 453 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.
