www.1.fm,

Now we know that the ccTLD domain names, afew of them listed above, are the shortest domains. So any single digit or letter email id in any of those domains would be the shortest. For example, x@1.fm or y@k.st would be one of the shortest email ids.

Since the maximum length of a domain label is defined as 63 characters, there also will be many websites with the longest domain names. If you want, you can as well create one! I think that the subdomains or top level domain suffixes should be counted for the largest domain name.

Here is the list of a few longest domains.
