I'm totally lost here. I was trying to set up the whois gem according to the documentation at https://whoisrb.org/. Unfortunately I'm always getting an error when trying to perform a whois, locally on my machine.
Error message:
Unable to find a WHOIS server for `;; answer received from 192.168.178.1 (75 bytes) ;; ;; security level : unchecked ;; ->>header<<- opcode: query, status: noerror, id: 51102 ;; flags: qr rd ra cd; query: 1, answer: 1, authority: 0, additional: 1 opt pseudo-record : payloadsize 512, xrcode 0, version 0, flags 32768 ;; question section (1 record) ;; google-public-dns-b.google.com. in a ;; answer section (1 record) google-public-dns-b.google.com. 84453 in a 8.8.4.4 '
Don't get confused, I'm using the dnsruby gem as well.. The corresponding code in my model:
def set_isp
res = Resolver.new
a_record = res.query(self.domain_name)
whois = Whois::Client.new
rec = whois.lookup(a_record)
self.isp = rec.name
end
Thanks a lot in advance!
According to the error, the issue is that you are passing the result of
a_record = res.query(self.domain_name)
straight to
whois.lookup
but the content of the a_record is not a domain name. Instead, it's a full DNS response:
;; answer received from 192.168.178.1 (75 bytes)
;;
;; security level : unchecked
;; ->>header<<- opcode: query, status: noerror, id: 51102
...
Please make sure the input is a valid domain name (or IP address).
