Whois with a list of domain names but got error "No whois server is known for this kind of object

I got the error message "No whois server is known for this kind of object." When I had my script run.

#!/bin/bashdomain_list="input.txt"while read linedo        name=$line        echo $name        whois $name        sleep 2done < input.txt

But if I check each line of the input.txt individually as follow it worked !!whois exmaple.com

• UPDATE ANSWER

while IFS=$' \t\r\n' read -r line
