Summary
D&P Communications
isp telecom business
Three identifiers carry dates, and the reverse names distinguish three generations of access technology.
What it's used for
- A rural telephone and broadband cooperative. 20,736 addresses across five IPv4 prefixes, the IPv6 block
2604:f200::/32, and three observed BGP neighbours.
Notable
- The AS handle is
DPCOM-ASN05222010, ending in a date. - Netnames
DPCOMM-12022010andDPCOMM-11072008each end in another date. - Hostnames name the access medium: one zone says fibre to the home, one says a fixed wireless standard, and two say cable modem pool.
64.112.192.0/19is netnameTC3NET, registered to a company with a different name.207.190.172.0/24is netnameLMTC, registered to a technology consortium.- Registrants list three roles after semicolons: abuse, technical and administration.
Interesting
- Dates in three separate identifiers make this one of the few networks in the range where the registry records when things happened. Each date marks a separate acquisition of space, years apart.
- Publishing the access technology per address means a reader can tell which customers are on fibre and which are on the older wireless standard without asking. One of those technologies has been effectively retired, and the zone still says so.
- A cooperative carrying an acquired company's netname and a school consortium's block is the rural pattern again: address space follows mergers and partnerships rather than tidy allocation.

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: 431 networks and 1,768 prefixes, as published 2026-10-12. 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.
