The domain list export contains every .bg domain webXtrend knows, 91,671 today, one name per line, together with all other TLDs. To keep only .bg: zgrep '\.bg$' domains.txt.gz > bg.txt. New .bg domains come every day with the daily new-domain file, and the API answers for any single domain: DNS history, redirects, reverse IP and the start page. The list is compiled by webXtrend from its own web crawl. Zone files for all TLDs
Counts are the domains webXtrend knows, from its own measurement of the public domain name space. They are not the registry's figures: where a registry does not publish its zone, our count can be lower than its own. Registry facts come from the IANA root zone database.
