About this network

NASK-COMMERCIAL is the commercial network of NASK, Poland's Naukowa i Akademicka Sieć Komputerowa — the National Research Institute that built the country's first internet connectivity. NASK is a state research institute, but this particular AS is its commercial ISP arm, distinct from its academic and registry roles.

What it's used for

• Internet access and IP transit sold to Polish businesses, public administration and smaller regional operators. Around 68 downstream ASNs sit behind it, which is a real customer cone rather than a stub.
• Reverse DNS shows both sides of that. Backbone and NOC hosts appear as SITE-gw-INTERFACE.warman.nask.pl (WARMAN is NASK's Warsaw metropolitan network) and dc11-gw-01.noc.nask.pl, while customer ranges resolve onto entirely unrelated Polish domains: regional ISPs, clinics and local companies.
• The AS carries several old /16s, including 193.59.0.0/16, 194.92.0.0/16, 194.181.0.0/16 and 195.164.0.0/16.

Notable

• Do not read customer addresses as NASK's own. Much of this space is assigned out to downstream businesses and operators, so a hostname or an organisation found in it usually belongs to a customer, not to the institute.
• NASK's better-known activities live elsewhere: it operates the .pl domain registry and hosts CERT Polska, Poland's national computer emergency response team. This AS is the commercial connectivity business that sits alongside them.
• The large classful-era holdings and the low AS number reflect NASK's origins as the organisation that first put Poland on the internet.
