Match domain names except one

Anonymous Monk has asked for the wisdom of the Perl Monks concerning the following question:

Input 
https://www.abc.com.wi.pr.com/
https://www.abc.com/
https://www.def.com.wi.pr.com/
https://www.wt.com.wi.pr.com/
[download]

There are many URL's but we should not match with the string (wt).

https?://(www.)?(abc|def).com[^/]*/?$
[download]

Hard coding works but there are many names which is not possible,

Trying to use the regex something like this but no luck :(

https?://(www.)?(.*)(?!wt).com[^/]*/?$
[download]

Please help me.
