 You can use the following command to automatically give you a ready-to-use list:
 
 ```bash
-curl -sL ip.guide/AS"$(curl -sL ip.guide | jq -s --indent 1 ".[].network.autonomous_system.asn")" | jq -s -j --indent 1 ".[].routes" | sed "/v4/d;/v6/d;/\],/d" | tr -d " [{]\",}"
+curl -sL ip.guide/AS"$(curl -sL ip.guide | jq -s --indent 1 ".[].network.autonomous_system.asn")" | jq -s -j --indent 1 ".[].routes" | sed "/v.*:/d;/\],/d" | tr -d " [{]\",}"
 ```
