I have many websites, registered in Google Webmaster Tools. When I check the backlinks, all of them are clean, except one website, which has close to 100,000 spammy links from Russian porn sites, etc. I want to use the Disavow Tool.

I have learned that I upload a .txt file, with #commentary and the URLs I want to disavow. In this case, I want to disavow entire domains, since each Russuan.ru (or other foreign country) domain gives me thousands of links. But some domains have subdomains.

I downloaded the links file, as instructed by Google. Here are examples of actual URLs with different subdomains.
bestrflex.zzz.com.ua/cat-1-24.php
boenau.zzz.com.ua/dir.php?id=131932
viehayg.zzz.com.ua/page-937717.php

My technical question is: if I disavow the domain, will that cover all subdomains? Example of the text I want to put in the .txt file:

# I do not recognize this domain. Attempted to reach webmaster. There is no way to reach a webmaster to ask for link removal. No registry data accessible.
domain:zzz.com.ua

Will that disavow all subdomains in this example? I'd hate to do them all manually, as there are often hundreds of subdomains (and thousands of URLs)

Thank you!

I didn't find the right solution from the internet.
