      I'm looking for a command line tool to make BGP Lookups such:

      https://www.dan.me.uk/bgplookup

      or

      http://bgp.he.net/AS3352#_prefixes

      The objective is to automatically build URL tables for pfSense aliases:

      Enter a single URL containing a large number of IPs and/or Subnets. After saving pfSense will download the URL and create a table file containing these addresses. This will work with large numbers of addresses (30,000+) or small numbers.

      I know that that BGP lookups need to query a router BGP capable. I'm doing this operation in another webserver than pfSense.

      I'm wondering if Quagga OSPF or OpenBGPD packages could help about it.

        Would this work for you?

        Its returning more than the 30 prefixes shown on the site? Maybe needs some tweaking.

        **curl -s https://www.dan.me.uk/bgplookup | grep  -o -P '(?<=">   ).(?=  <td)'< strong="">```

          @ BBcan17,

          Thanks for your advice!

          In fact, many BGP lookups have a lot of prefixes that included others. I don't know why. It would be better to "compress" their notation by CIDR.

          Until know I did manually, but it is a lot of work, I can do mistakes and is not automatic (by scripting).

          Unfortunatelly, https://www.dan.me.uk/bgplookup seems to work without parameters in the URL. I don't know how to use it in scripting.

          I wrote this using http://bgp.he.net/ and it works for me:

          #!/bin/sh
          #
          # Generates IPv4 prefixes for one AS (http://en.wikipedia.org/wiki/Autonomous_System_%28Internet%29)
          # Josep Pujadas-Jubany (15-mar-2014)
          #
          # Example for AS19679:
          # ./as.sh 19679
          # generates as19679.txt
          #
