AS44489 STARNET
Residential RIPE Cable/DSL/ISP
Summary
Starnet
isp residential cable dsl
The AS handle STARNET is operated by Starnet, s.r.o.
What it's used for
- The address space carries residential and business internet services, evidenced by netnames such as
CZ-STARNET-20091014,CZ-GREPA-20060609, andCZ-SOFTEXNCP-20080826, and reverse DNS entries pointing toaddr.grepnet.cz. - With 64,768 IPv4 addresses announced across 29 prefixes and 26 observed neighbours, the ratio indicates an access network providing connectivity to end-users rather than a transit provider.
- Traffic from this AS consists of subscriber eyeballs, including wireless internet distribution to end customers, as Starnet operates as a regional cable/DSL/ISP in Czechia.
Notable
- Registrants include STARNET, s.r.o., SOFTEX NCP, s.r.o., GREPA Networks s.r.o., and inet4 s.r.o., reflecting a portfolio of acquired or leased address blocks under the Starnet umbrella.
- The address inventory is finely subdivided into multiple /21 and /22 blocks, consistent with a regional ISP managing distinct customer segments or legacy acquisitions.

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: 442 networks and 1,773 prefixes, as published 2026-10-13. 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.
