Possible extension for NetblockTool ?

[ummeegge]

Hi all,
since i am currently testing some tools for blocking companies via an IPFire firewall, i wanted to made some tests according to the information gathering of CIDRs, ASNs and IPs . Have used therefor NetblockTool-2.1.0 and libloc (location 0.9.16) . A fast test to gather information about 'Cloudflare's CIDRs with both tools delivers the following results

$ wc -l cloudflare_cidrs_*
 2201 cloudflare_cidrs_libloc
  154 cloudflare_cidrs_netblocktool

whereby i´ am not 100% sure how this difference comes up. If you are interested testing this on your side, libloc should be available for Debian and Fedora, libloc comes also with native Python bindings so i thought i leave you a note about this.

Hope this is a useful contribution.

Best,

Erik
