I am trying to use the ruby whois gem but the whois-parser gem doesn't seem to work for .dev i.e for these I get Whois::AttributeNotImplemented errors and doesn't return some details like the expiry date for .co domains, in this case, it returns nil. I understand that there is probably no parser for .dev domains but not sure what's wrong with .co domains. I am new to all this and even willing to implement a parser. What are possible solutions, I can look at?
Turns out the whois-parser gem is no longer maintained and this fork https://github.com/jarthod/whois-parser solves this issue.
