About this network

SLOVANET-BROADBAND is the broadband access network of Slovanet a.s., one of Slovakia's larger alternative telecoms operators. This AS carries the company's subscriber access, as distinct from its corporate and infrastructure networks.

What it's used for

• Roughly 83,000 addresses across thirteen prefixes.
• The reverse DNS is textbook eyeball addressing, and it names the access technology in the zone: 85-135-192-NN.adsl.slovanet.sk for DSL lines, 176-61-192-NN.wmx.slovanet.sk for the WiMAX/fixed-wireless estate, 178-253-170-NN.vdial.slovanet.sk for dial-style access, and 188-112-64-NN.3pp.slovanet.sk.
• The newer 185.37.240.0/22 resolves to NN.cgn-stl.slovanet.sk — carrier-grade NAT, so many subscribers share each address there.

Notable

• Residential and small-business access space. An address here is a Slovak home or small office, and the technology label in the hostname tells you which access product it sits behind.
• The CGN block matters for attribution: addresses in it are shared across many subscribers, so a single IP does not identify one household.
