What's new in WHOIS.C.NF 4.0?
WHOIS.C.NF version 4.0 supports High Fault-tolerant Input (HFI).

What is High Fault-tolerant Input (HFI)?
In WHOIS.C.NF v1.0, you are not allowed to enter the URL (domain name with http/https:// protocol).
But, in WHOIS.C.NF 4.0,you can input like [ https://WHOIS.C.NF ], it will whois and clear the protocol directly.

Here are some more Fault-tolerant Input (HFI) examples at below:

http://WHOIS.C.NF --> WHOIS.C.NF
https://WHOIS.C.NF --> WHOIS.C.NF
https://WHOIS.C.NF/log --> WHOIS.C.NF
http://WHOIS.C.NF/index.html --> WHOIS.C.NF
http://whois。C。NF --> WHOIS.C.NF
whois。C。NF/log --> WHOIS.C.NF
It's real, Try it yourself >>>

Protocol like http:// or https:// is default neglected by WHOIS.C.NF v4.0
www before the domain is neglected in specific situation.
File /path/ after the domain name is neglected.

http://WHOIS.C.NF --> WHOIS.C.NF
https://WHOIS.C.NF --> WHOIS.C.NF
https://WHOIS.C.NF/log --> WHOIS.C.NF
http://WHOIS.C.NF/index.html --> WHOIS.C.NF
http://whois。C。NF --> WHOIS.C.NF
whois。C。NF/log --> WHOIS.C.NF
It's real, Try it yourself >>>
