IPV6 Lookup Fails

[Takeda0x64]

Explanation

When performing a WHOIS lookup using the whois.lookup() function on an IPv6 address (e.g., 2001:4860:4860::8888), the response is returning No match found. However, when executing the same lookup using the WHOIS command in the CLI, the correct information is displayed, such as the net range, organization details, and relevant WHOIS data.

Expected Behavior: The node-whois module should return complete and accurate WHOIS information for IPv6 addresses, similar to what is received via the CLI.

Actual Behavior: The module returns incomplete or incorrect results when querying IPv6 addresses

Steps to Reproduce:

1- Call the method wiht Ipv6 input (e.g., 2001:4860:4860::8888) :

whois.lookup("2001:4860:4860::8888", (err,data) =>{
    console.log(data);
})    

The output is :

Perform the same lookup using the whois CLI:

whois 2001:4860:4860::8888

I created a patch to resolve the bug, and now everything works as expected. The issue was in the domainToASCII function, which returns an empty string when passed an IPv6 address.

if server.punycode isnt false and options.punycode isnt false
       idn = url.domainToASCII(addr)
if options.encoding
       socket.setEncoding options.encoding
       socket.write server.query.replace '$addr', idn

The patch sets both server.punycode and options.punycode to false, ensuring that they do not pass the condition check so domainToASCII will not be invoked if IPv4 or IPv6 is passed :

when net.isIP(addr) isnt 0
   server = @SERVERS['_']['ip']
   server.punycode = false
   options.punycode = false

Also IPV6 test passes

 ✔ should work with google.com
 ✔ should work with 50.116.8.109
 ✔ should work with 2001:0db8:11a3:09d7:1f34:8a2e:07a0:765d
 ✔ should honor specified WHOIS server
 ✔ should honor specified WHOIS server with port override
