Are there email addresses ending in ".con"?

Question

I've noticed that there are a lot of users that misspell their email addresses when registering. For example, if the email is [email protected], the user may write [email protected]. In a registering process, this may lead to the user registering wrong without him/her being aware of.

Is it a good idea to implement a function that changes .con for .com? This would be a problem if .con email addresses exist because they wouldn't be able to register. Do .con email addresses exist?

Answer 1

.con emails cannot exist (right now) because there is not a top-level domain (TLD) named .con

If you go to the Wikipedia page or tld-list.com, you'll see that there isn't a .con

• .computer
• .condos
• .construction
• .consulting
• .contact
• .contractors
• .cooking

No .con to be found.

You should probably popup a warning instead of automatically fixing it, though, so that clients are conscious that they made a mistake.

Answer 2

As of today, there is no .con top-level domain (according to https://en.wikipedia.org/wiki/List_of_Internet_top-level_domains#C ).

Is it a good idea? That's more of a Product question than a technical question :) Maybe just prevent the user from entering such an address using client-side validation instead of replacing it for them automatically?
