How to resolve blockchain dns using Python Requests

0 votes

There are certain blockchain domains that are resolved only by blockchain DNS resolvers. If you try to open this link in a browser, it won't get resolved.

But, just install the browser plugin from https://blockchain-dns.info/ and then try to open the site again, it will open up smoothly.

I want to scrape some data from this site using Python Requests (browserless) and have no idea how to resolve such blockchain domains. Any help would be highly appreciated.

BDNS is offline and I don't know if they'll be back. I searched for similar public HTTP APIs but couldn't find one that works well enough. Preferably, we can use Dnspython to query an OpenNIC server.

import dns.resolver import requests def domain_to_ip(domain, dns_server='159.89.120.99'): '''Uses an OpenNIC server to resolve blockchain domains :param domain: str Domain or URL :param dns_server: str Optional, OpenNIC server :raises dns.resolver.NXDOMAIN: if `dns_server` fails to resolve `domain` ''' if '://' in domain: domain = domain.split('/')[2] res = dns.resolver.Resolver() res.nameservers = [dns_server] answers = res.resolve(domain) return [rdata.address for rdata in answers] ips = domain_to_ip('http://track2.bazar') if ips: r = requests.get('https://'+ips[0], verify=False) print(r)
