Get IP range by AS number

[viktor_g]

Found useful site for this https://hackertarget.com/as-ip-lookup/

You can simply add IPv4 feed:
https://api.hackertarget.com/aslookup/?q=AS15169

But is more better to have native ability in pfBlockerNG, and get ip ranges from radb.net
like this script:
whois -h whois.radb.net -- '-i origin AS15169' | grep -Eo "([0-9.]+){4}/[0-9]+"

@viktor_g your script only does IPv4

IPv4:-

whois -h whois.radb.net -- '-i origin ASS15169' | grep ^route: | awk '{print $2}'

IPv6:-

whois -h whois.radb.net -- '-i origin AS15169' | grep ^route6: | awk '{print $2}

pfBlockerNG-devel already has ASN support in the IP State setting. Also Radb registry isn't very accurate. The package is using bppview.io instead.
