Hello friends,

What is best and quick way to increase DA..?

Domain authority is the measure of strength and popularity of your domain in search engines. It is measured by Moz and your domain is ranked between 0 to100 depending on the popularity and trust. DA can be improved by good content update and also by building backlinks from other relevant domains.

You need to take good care of the content of the website, the DA will increase you. But the DA has long been updated for months, so you should stick to good content.
