IRRTree

Simple tool to quickly assess potential resource consumption of an AS-SET.

job$ irrtree
IRRtool v1.1.0
usage: irrtree [-h host] [-p port] [-l sources] [-d] [-4 | -6] [-s ASXX] <AS-SET>
   -d,--debug          print debug information
   -4,--ipv4           resolve IPv4 prefixes (default)
   -6,--ipv6           resolve IPv6 prefixes
   -l,--list=SOURCES   list of sources (e.g.: RIPE,NTTCOM,RADB)
   -p,--port=PORT      port on which IRRd runs (default: 43)
   -h,--host=HOST      hostname to connect to (default: rr.ntt.net)
   -s,--search=AUTNUM  output only related to autnum (in ASXXX format)

Note: especially when dealing with large AS-SETs, the latency towards the IRRd host has significant impact on this program's execution time. Lower latency is better.

Installation:

irrtree requires python 3

Through pypi (try pip install --upgrade pip if you get errors):

$ pip install irrtree

From source:

git clone https://github.com/job/irrtree.git
cd irrtree
pip install 'pip>1.5' --upgrade
python setup.py install

Examples

Display structure of AS-COLOCLUE, counting IPv6 prefixes:
