Domain names are often seen in analogy to real estate in that domain names are foundations on which a website can be built, and the highest quality domain names, like sought-after real estate, tend to carry significant value, usually due to their online brand-building potential, use in advertising, search engine optimization, and many other criteria.

The character set allowed in the Domain Name System is based on ASCII and does not allow the representation of names and words of many languages in their native scripts or alphabets. ICANN approved the Internationalized domain name (IDNA) system, which maps Unicode strings used in application user interfaces into the valid DNS character set by an encoding called Punycode. For example, københavn.eu is mapped to xn--kbenhavn-54a.eu. Many registries have adopted IDNA.


Before you sign up for a WordPress web hosting service, you should look for these attractive—and possibly essential—features. Ideally, you'll want to invest in a WordPress host that provides unlimited monthly data transfers, email, storage, and 24/7 support. Many WordPress web hosts that place caps on those features, particularly on the managed side of things. WP Engine ($35.00 - 20% Off with Promo Code PCMAG20 at WP Engine) , for example, limits sites to 400,000 visitors and a relatively paltry 30GB of storage. If you expect lots of site growth, you'll want a host that can properly accommodate your website's future expansion.
The managed variety the white-glove treatment with four tiers of Linux-based WordPress hosting. Signing up has its advantages. GoDaddy has thousands of WordPress themes and plug-ins, and it offers nightly backups and automatic WordPress software updates. Like other managed WordPress hosts, GoDaddy doesn't require you to install the CMS, as it comes preinstalled. Once you're logged into WordPress, you can create posts, pages, and galleries as you would with any other self-hosted WordPress site.
A domain name consists of one or more labels, each of which is formed from the set of ASCII letters, digits, and hyphens (a-z, A-Z, 0-9, -), but not starting or ending with a hyphen. The labels are case-insensitive; for example, 'label' is equivalent to 'Label' or 'LABEL'. In the textual representation of a domain name, the labels are separated by a full stop (period).
Web hosting services, on the other hand, run servers that are typically assigned only one or a few addresses while serving websites for many domains, a technique referred to as virtual web hosting. Such IP address overloading requires that each request identifies the domain name being referenced, for instance by using the HTTP request header field Host:, or Server Name Indication.
