This is a simple tool to pull all netblocks from an ASN into a text file output.
This is useful for situations like using URL Alias setups on pfSense routers.
You can request a combined ASN response by seperating each ASN with a ":", see example below.
It can be used to find all IPs used by a service or ISP, examples:
