ASN support

[atlassion]

Add function Whois from files IPASN.DAT, asn.json like
pyasn : https://github.com/hadiasghari/pyasn/

Example for python:
pyasn_util_asnames.py > asn.json; pyasn_util_download.py -4; rib=$(ls -t rib.*.bz2 | head -1); pyasn_util_convert.py --single $rib IPASN.DAT; rm -f $rib

import pyasn
asndb = pyasn.pyasn('IPASN.DAT',as_names_file='asn.json')
#whois
asn,cidr = asndb.lookup(ipaddrr)
asn_name = asndb.get_as_name(asn)
Who = f"{cidr} AS{asn} {asn_name}"
print(Who)

ip google for example:

[142.250.187.206 142.250.0.0/15 AS15169 GOOGLE, US]

Suggested or similar maintained FOSS library/project can be used to process ASN information passively on IP data of httpx.

echo google.com | httpx -asn -silent
https://google.com [AS15169, GOOGLE, 172.217.0.0/16,142.250.0.0/15]

echo google.com | httpx -asn -silent -json
