Poland's .pl: 22.25 Million Hostnames, 2.61 Million Registrations, and the ccTLD That's Forty Percent ISP Reverse-DNS
We analyzed 22.25 million .pl hostnames in our 17 April 2026 active crawl against NASK's 2.61 million registered domains to find that Poland's namespace is dominated by ISP reverse-DNS infrastructure to a degree few European ccTLDs match: Orange Polska's three reverse-DNS zones alone account for 18.1 percent of every observable .pl hostname, and twenty-eight operators together generate over nine million entries. Beneath the infrastructure layer sits a frozen ecosystem of mid-2000s Polish-language platforms — digart.pl, fora.pl, pinger.pl, republika.pl — that still resolve in 2026, and a regional architecture of twenty-three city and voivodeship second-level domains that NASK launched in the 1990s and that, three decades on, account for under 1.5 percent of the namespace.
