Summary
PenTeleData
isp legacy
PenTeleData (AS-PTD), a regional internet service provider based in Palmerton, Pennsylvania, serving eastern Pennsylvania and neighbouring parts of New Jersey.
What it's used for
- Consumer and business internet access — the AS carries broadband subscribers delivered over the cable and fiber plant of PenTeleData's partner operators.
Notable
- An eyeball network: the roughly 685,000 IPv4 addresses announced here are overwhelmingly home and small-business customers, not servers.
- The holding includes legacy blocks such as
204.186.0.0/16,70.44.0.0/16, and75.97.0.0/16alongside newer cable-era/17s and/18s. - PenTeleData was formed as a joint venture of local cable television companies, which is why one AS fronts internet service branded under several different regional providers.
Interesting
- It is a rare survivor: an independent, locally owned regional ISP still running its own backbone in a market otherwise consolidated into national cable and telco brands.

Classification and threat
Residential Fixed-line consumer ISP. Addresses here are homes.
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.
