Thanks for replying Matt and good catch on the nameserver IP - it was
a typo. Unfortunately, I get the exact same connection error message
from Heroku when using an IP that dig has no problem connecting to
(e.g. Google's public DNS server 8.8.8.8):
>> res = Dnsruby::Resolver.new({:nameserver => "8.8.8.8"})
...
>> ret = res.query('www.abc.com')
Errno::ECONNREFUSED: Connection refused - connect(2)
>> puts `dig www.abc.com @8.8.8.8`
; <<>> DiG 9.6-ESV-R3 <<>> www.abc.com @8.8.8.8
;; global options: +cmd
;; Got answer:
...
Any ideas?
