I've a query with regards to CNAME record, can I have a CNAME as different domain name? Ex. I've a website example.com, can I create a CNAME with example.net? So, irrelevant of what end user types (either example.com or example.net) they should always reach example.com

Two issues collide here. The first is can a CNAME point to a different domain, to which the answer is yes, that is perfectly acceptable.
The second, though, is that in the case of your example, you cannot use a CNAME at all, because you cannot use a CNAME at the apex (aka root) of a domain. foo.example.net
can be a CNAME; example.net
cannot.

This may be dangerous to suggest to inexperienced admins, but there are `ALIAS` and `ANAME` records which can be attached to the root domain and provide *similar* behavior to a `CNAME`. With that said, *make sure you know what you are doing* before deploying these types of records. – Brennen Smith Aug 18 '16 at 07:34

1@Brennen It also needs to be mentioned that `ALIAS` and `ANAME` are *not* record types defined by the standards. They are custom behavior in certain server implementations. – Andrew B Aug 19 '16 at 02:42
If you're just trying to redirect example.net web site visitors to example.com , that's what you should do. Point example.net A DNS record to example.com's IP address. After that, you have a couple of options;
-Create a new website on your host that accepts example.net visitors and redirect them using HTML/Javascript in your index page , or using your server's redirection capabilities.
-On your single website, check to see if visitors' URL matches example.net and redirect them to example.com using Javascript in your index page.
Pick one.

Or you could just use a ServerAlias and not have to worry about all the coding and redirects. – user9517 Aug 18 '16 at 06:52

1Does it change the URL tho? If it's something like "Host headers" in IIS, URL will stay "example.net" . – Mer Aug 18 '16 at 06:58
