: Why in the modern world I would need my .com website to also have www subdomain? Recently I registered a .com address for a business. In the modern world (year 2018) why would I need to

@Nimeshi995

This answer contains my comment and then @dan 's comment. Both show two different thoughts on the subject. Combined, they make a good answer. Any other points are certainly welcome.

The value of www is that people will likely type it automatically. If I understand you correctly, you are asking, What is the point of having www these days when it really is not necessary? If that is the case, and assuming your site is actually on example.com, the www is a user friendly thing to do. It is not required, never was, but a good idea still.

If you're not asking this in relationship to SEO or why it's technically used, then it's really just a matter of preference as to which to use. Large sites tend to use www to separate the main site from other sub-domains (e.g., for different types of content and languages) and protocols (e.g., ftp). Using www as a host also helps with the flexibility of DNS management and the ability to restrict cookies when using multiple sub-domains. That of course borders on the technical explanation however... Once you pick one, then you should stick to that and direct the other to it.
