Summary
Quantcom
residential isp czech dial
QUANTCOM-AS is operated by Quantcom, a.s., a Czech telecommunications provider formerly known as Dial Telecom.
What it's used for
- The address space carries residential broadband access, evidenced by reverse DNS entries such as
prg1-1-1-volnydslnet1.vol.czandprg1-adslplusctcnet7.vol.cz, which reference DSL and static IP services. - With 265,984 IPv4 addresses announced across 38 prefixes and 733 observed neighbours, the high neighbour count relative to the address inventory indicates a transit or peering-heavy role, consistent with a national ISP providing upstream connectivity.
Notable
- Registrants for the majority of prefixes are listed as "Dial Telecom Hostmaster Role" and "Quantcom, a.s.", reflecting the company's rebranding from Dial Telecom to Quantcom.
- One prefix, 46.33.96.0/19, is registered to "INFOS Art, s.r.o.", which differs from the primary registrant and may indicate leased space or a separate entity.
- The inventory includes a mix of /17, /18, and /19 blocks, with the largest being 88.146.0.0/17, alongside 19 IPv6 prefixes.

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: 432 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.
