How to match regex for TLD?

Question

I know there are lot of regex for the purpose, but in my case the regex i want to write is one that matches following payload

 ...............sssfdf.makememad.com...... ........makemadcom..... dfdfddd makeme.ru....... also ...makeme.net.......

I just want to match anything with following

.ru .net .com

And due to some limitations of the software in which im using the regex it won't allow to do this

\.

so any regex which skips this would be great.

Thanks.

How do you escape a period then in your engine then, what engine are you using? Also that looks like the text dump from a hex editor. Are all those periods really periods or are they really unprintable text from a hex editor. Please provide more detail about how you are trying to do what you want to do. I would put money that whatever language you are using uses \ as a escape character so you need to escape the escape via something like "\\." — Scott Chamberlain

the engine works fine on other traffic but one particular application traffic e.g dns it won't work. Its closed system SIEM solution. The engine uses java regex — asadz

Use a character class since you don't need to escape:

[.](ru|net|com)
