Residential RIPE Cable/DSL/ISP
Summary
DPT s.r.o.
isp residential czechia cable
The AS handle DPT is held by DPT s.r.o., a Czech regional internet service provider.
What it's used for
- The address space carries residential and business customer traffic, evidenced by reverse DNS entries like
ip-89-190-37-254.dpt.czand netnamesCZ-DATONET-20030327andCZ-DATONET-20141017. - The network announces 3,072 IPv4 addresses across 2 prefixes and 1 IPv6 prefix, while maintaining 27 observed neighbours; this ratio indicates a regional access network rather than a transit provider.
- Traffic consists of subscriber eyeballs and local business endpoints served via cable and DSL infrastructure in the Czech Republic.
Notable
- Registrants for both announced prefixes list "Datonet Admin" and "DPT s.r.o.", confirming the AS is operated by the same entity that holds the address space.
- The operator is also known as Datonet, as indicated by PeeringDB aliases and the netname history.
- The inventory is compact, consisting of two IPv4 blocks and a single IPv6 prefix, all located in Czechia.

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: 449 networks and 1,846 prefixes, as published 2026-11-02. 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.
