drwho's Introduction

drwho - concurrent 'whois' queries

given a set of ip addresses (v4 and v6), concurrently queries whois servers about them.

example

  1. populate a file with one ipv4 addr per row
$ cat ips.txt
162.250.189.53
163.172.62.166
168.119.12.182
170.130.55.119
172.86.181.178
  1. point drwho at such file
$ drwho -f ips.txt
162.250.189.53,Rica Web Services
163.172.62.166,ERX-NETBLOCK
168.119.12.182,RIPE Network Coordination Centre
170.130.55.119,Eonix Corporation
172.86.181.178,Joe's Datacenter, LLC

but really, why?

recently, there's been some sus activity in monero's network, so being able to get (maybe) useful extra information about connections/peers seemed interesting.

$ monero daemon get-connections --json | \
  jq '.connections[] | .address' -r | \
  awk -F':' '{print $1}' | \
  drwho -f- --concurrency=20
