Async dnsbl lists checker based on asyncio/aiodns. Checks if ip is listed in anti-spam dns blacklists. Multiple dns blacklists supported. Use aiodns for async dns requests. Usually ip check run for 50 lists takes less than one second. Also allow to check domains.

pip install pydnsbl

• python >= 3.5
• aiodns

>>> import pydnsbl
>>> ip_checker = pydnsbl.DNSBLIpChecker()
>>> ip_checker.check('8.8.8.8')
<DNSBLResult: 8.8.8.8  (0/52)>
>>> ip_checker.check('68.128.212.240')
<DNSBLResult: 68.128.212.240 [BLACKLISTED] (6/52)>

>>> import pydnsbl
>>> domain_checker = pydnsbl.DNSBLDomainChecker()
>>> domain_checker.check('google.com')
<DNSBLResult: google.com  (0/4)>
>>> domain_checker.check('belonging708-info.xyz')
<DNSBLResult: belonging708-info.xyz [BLACKLISTED] (2/4)>

• DNSBLResult.addr - ip address or domain that was checked
• DNSBLResult.blacklisted - boolean, True if ip/domain detected by at least one provider
• DNSBLResult.detected_by - dictionary containing providers hosts detected this ip/domain as keys and their category verdicts
• DNSBLResult.categories - combined categories from all providers for this ip/domain
• DNSBLResult.providers - list of providers that was performing the check
• DNSBLResult.failed_providers - list of providers that was unable to check this ip properly (possibly provider was down)

>>> result = domain_checker.check('belonging708-info.xyz')
>>> result.addr
'belonging708-info.xyz'
>>> result.blacklisted
True
>>> result.detected_by
{'multi.surbl.org': ['unknown'], 'dbl.spamhaus.org': ['spam']}
>>> result.categories
{'unknown', 'spam'}
>>> result.providers
[<Provider: uribl.spameatingmonkey.net>, <Provider: multi.surbl.org>, <Provider: rhsbl.sorbs.net >, <Provider: dbl.spamhaus.org>]
>>> result.failed_providers
[]

 
from pydnsbl import DNSBLIpChecker, providers
from pydnsbl.providers import BASE_PROVIDERS, Provider
providers = BASE_PROVIDERS   [Provider('yourprovider1.com'), ...]
checker = DNSBLIpChecker(providers=providers)

Take a look into providers.py file.

• Use Provider class to create your custom providers.
• Override process_response method of Provider class to map providers response codes (127.0.0.x) to DNSBL categories.
