aiodnsbl

DNSBL lists checker based on aiodns. Checks if an IP or a domain is listed on anti-spam DNS blacklists.

Notes

This is a fork of pydnsbl.

Key differences:

• Fully type annotated
• No sync wrapper (async only)
• No category classification

Installation

pip install aiodnsbl

Usage

import asyncio

from aiodnsbl import DNSBLChecker


loop = asyncio.get_event_loop()

checker = DNSBLChecker()

# Check IP
loop.run_until_complete(checker.check("8.8.8.8"))
# <DNSBLResult: 8.8.8.8  (0/10)>
loop.run_until_complete(checker.check("68.128.212.240"))
# <DNSBLResult: 68.128.212.240 [BLACKLISTED] (4/10)>

# Check domain
loop.run_until_complete(checker.check("example.com"))
# <DNSBLResult: example.com  (0/4)>

# Bulk check
loop.run_until_complete(
    checker.bulk_check(["example.com", "8.8.8.8", "68.128.212.240"])
)
# [<DNSBLResult: example.com  (0/4)>, <DNSBLResult: 8.8.8.8  (0/10)>, <DNSBLResult: 68.128.212.240 [BLACKLISTED] (4/10)>]

import asyncio

from aiodnsbl import DNSBLChecker


async def main():
    checker = DNSBLChecker()
    res = await checker.check("68.128.212.240")
    print(res)
    # <DNSBLResult: 68.128.212.240 [BLACKLISTED] (4/10)>
    print(res.blacklisted)
    # True
    print([provider.host for provider in res.providers])
    # ['b.barracudacentral.org', 'bl.spamcop.net', 'dnsbl.sorbs.net', 'ips.backscatterer.org', ...]
    print([provider.host for provider in res.detected_by])
    # ['b.barracudacentral.org', 'dnsbl.sorbs.net', 'spam.dnsbl.sorbs.net', 'zen.spamhaus.org']
