null response for .ch domains

[deepika-maj]

the library is returning null response for .ch domains, for eg: swissinfo.ch

Hmm, cant request via linux whois:

Looks like .CN does not support standard whois protocol

[deepika-maj]

the cli command whois swissinfo.ch -h whois.nic.ch works within my mac terminal however it does not work on an ubuntu like you said. seems like a strange issue within that whois server

In my experience is not possible make a whois on whois.nic.ch on port 43, you must use the web page protected by a captcha.

It's possible to make a domain check using whois.nic.ch on port 4343 (https://www.nic.ch/whois/domaincheck/) whois swissinfo.ch -h whois.nic.ch -p 4343 returns a custom response to indicate the status of the domain, I have not found other ways to not use the web page https://www.nic.ch/whois/ the Swiss are jealous of their whois

Very hard terms of use (section 2): https://www.nic.ch/terms/aup/ Maximum what can be done is custom parser for SWITCH. And simple checking domain is registered/free...
