About this network

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.cz and prg1-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.
