asyncwhois




asyncwhois | Python utility for WHOIS and RDAP queries.
Quickstart

import asyncwhois

# pick a domain
domain = 'bitcoin.org'
# domain could also be a URL; asyncwhois uses tldextract to parse the URL
domain = 'https://www.google.com?q=asyncwhois'

# basic example
query_string, parsed_dict = asyncwhois.whois(domain)
# query_string # The semi-free text output from the whois server
# parsed_dict # A dictionary of key:values extracted from `query_string`

# asyncio example
loop = asyncio.get_event_loop()
query_string, parsed_dict = loop.run_until_complete(asyncwhois.aio_whois(domain))

RDAP
The whodap project is used behind the scenes to perform RDAP queries.
domain = "https://google.com"
query_string, parsed_dict = asyncwhois.rdap(domain)
# OR with asyncio
query_string, parsed_dict = loop.run_until_complete(asyncwhois.aio_rdap(domain))

# Reusable client (caches the RDAP bootstrap server list, so it is faster for doing multiple calls)
client = asyncwhois.DomainClient()
for domain in ["google.com", "tesla.coffee", "bitcoin.org"]:
query_string, parsed_dict = client.rdap(domain)
# query_string, parsed_dict = await client.aio_rdap(domain)

# Using a proxy or need to configure something HTTP related? Try reconfiguring the client:
whodap_client = whodap.DNSClient.new_client(
httpx_client=httpx.Client(proxies="https://proxy:8080")
)
# whodap_client = await whodap.DNSClient.new_aio_client(httpx_client=httpx.AsyncClient(proxies="https://proxy:8080"))
client = asyncwhois.DomainClient(whodap_client=whodap_client)

Using Proxies
SOCKS4 and SOCKS5 proxies are supported for WHOIS and RDAP queries.
import whodap

tor_host = "localhost"
tor_port = 9050

# WHOIS
query_string, parsed_dict = asyncwhois.whois(
"8.8.8.8", proxy_url=f"socks5://{tor_host}:{tor_port}"
)

# RDAP
import httpx
from httpx_socks import SyncProxyTransport, AsyncProxyTransport # EXTERNAL DEPENDENCY for SOCKS Proxies

transport = SyncProxyTransport.from_url(f"socks5://{tor_host}:{tor_port}")
httpx_client = httpx.Client(transport=transport)
whodap_client = whodap.IPv6Client.new_client(httpx_client=httpx_client)
query_string, parsed_dict = asyncwhois.rdap('2001:4860:4860::8888', whodap_client=whodap_client)

transport = AsyncProxyTransport.from_url(f"socks5://{tor_user}:{tor_pw}@{tor_host}:{tor_port}")
async with httpx.AsyncClient(transport=transport) as httpx_client:
whodap_client = await whodap.DNSClient.new_aio_client(httpx_client=httpx_client)
query_string, parsed_dict = await asyncwhois.aio_rdap('bitcoin.org', whodap_client=whodap_client)

Contributions
Parsed output not what you expected? Unfortunately, "the format of responses [from a WHOIS server] follow a semi-free text format". Therefore,
situations will arise where this module does not support parsing the output from a specific server, and you may find
yourself needing more control over how parsing happens. Fortunately, you can create customized parsers to suit your needs.
Example: This is a snippet of the output from running the "whois google.be" command.

In this case, the "name servers" are listed on separate lines. The default BaseParser regexes
won't find all of these server names. In order to accommodate this extra step, the "parse" method was
overwritten within the parser subclass as seen below:
class RegexBE(BaseParser):
_be_expressions = { # the base class (BaseParser) will handle these regexes
BaseKeys.CREATED: r'Registered: *(.+)',
BaseKeys.REGISTRAR: r'Registrar:\n.+Name: *(.+)',
BaseKeys.REGISTRANT_NAME: r'Registrant:\n *(.+)'
}

def __init__(self):
super().__init__()
self.update_reg_expressions(self._be_expressions)

def parse(self, blob: str) -> Dict[str, Any]:
# run base class parsing for other keys
parsed_output = super().parse(blob)
# custom parsing is needed to extract all the name servers
ns_match = re.search(r"Name servers: *(.+)Keys: ", blob, re.DOTALL)
if ns_match:
parsed_output[BaseKeys.NAME_SERVERS] = [m.strip() for m in ns_match.group(1).split('\n') if m.strip()]
return parsed_output
