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.
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
