You can summarize all the IP ranges of a particular ASN using a combination of the paid IPinfo ASN API service, the IPinfo CLI and JQ.
This can also be done with our free IP to ASN database. If you are interested, please let me know! I will provide instructions as well.
This summary operation is interesting because it will show you the actual IP range locations of a particular ASN instead of the advertised ones in their WHOIS data. It also provides a bird’s eye view of the IP metadata of a particular ASN.
curl ipinfo.io/AS152586?token=$token | jq -r .prefixes[].netblock | ipinfo summarize
