The hierarchy of domains descends from the right to the left label in the name; each label to the left specifies a subdivision, or subdomain of the domain to the right. For example: the label example specifies a node example.com as a subdomain of the com domain, and www is a label to create www.example.com, a subdomain of example.com. Each label may contain from 1 to 63 octets. The empty label is reserved for the root node and when fully qualified is expressed as the empty label terminated by a dot. The full domain name may not exceed a total length of 253 ASCII characters in its textual representation.[6] Thus, when using a single character per label, the limit is 127 levels: 127 characters plus 126 dots have a total length of 253. In practice, some domain registries may have shorter limits.
A domain name is an identification string that defines a realm of administrative autonomy, authority or control within the Internet. Domain names are used in various networking contexts and for application-specific naming and addressing purposes. In general, a domain name identifies a network domain, or it represents an Internet Protocol (IP) resource, such as a personal computer used to access the Internet, a server computer hosting a web site, or the web site itself or any other service communicated via the Internet. In 2017, 330.6 million domain names had been registered.[1]
What about the time you clicked on that PayPal link that wasn't really a PayPal link? "Phishing" is a term applied to either websites or emails that pretend to be something they're not in hopes of getting a user to click on something they should have ignored. This tactis is done in hopes of then getting users to provide confidential information they would have otherwise kept to themselves, typically like passwords, financial information, or other personal data. While there are security measure that fight this, the mechanics behind phishing are, unfortunately, also consistently becoming more sophisticated. Even some dedicated antivirus and business-class hosted endpoint protection suites are having trouble keeping up.

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.
SpamExperts is the name of Bluehost’s spam management and advanced email administer tool. With it, email users can view a quarantined message, manage personal email settings, whitelists and blacklists and specify an incoming delivery queue as a way of reviewing and controlling incoming spam. The Plus plan is best for teams looking for email hosting services as well as a website hosting partner and more robust spam control.

If you’ve never build a website before and you want to become a web designer, this is a great place to start with its 503-minute HTML course.
Data protection is another key email security concern. Inboxes often contain GBs of business-critical and personal data, so not just hackers but also legitimate marketing companies can make big money off mining email data—and this sometimes includes the very company that is providing the email service to you. Fortunately, most companies, including your hosting provider, are pretty good about keeping out of private data, but it's important to be aware of when these policies have failed. Security breaches are commonplace and it's important to know how your data is being managed. To protect yourself, be sure to inquire about data safety capabilities on the provider's side, especially around encryption and malware scanning. But be sure to implement additional measures on your side, as well, including encryption for those using local email clients as well as deploying personal virtual private networks (VPNs) to folks accessing their email from multiple locations. 

The cloud certainly makes delivering email to your users easier but, for the vast majority of organizations, there's still going to be some setup required beyond simply activating the service. At a minimum, a domain must be purchased and configured to point to the new email host. The service provider can make this process very simple or they can make quite hard; this is something you should watch for in the provider's customer support forums as well as in our reviews. In most cases, there is a validation phase that will require some technical familiarity, though a few providers go so far as to walk even neophyte users through it step by step. Other solid services bolster excellent support with tutorial articles and videos that also walk you through the process. The worst will leave you to figure it out on your own.
The Gmail browser-based client within G Suite does not include bulk clean-up tools like those found in Zoho Workplace or Office 365. It also does not support multiple email signatures or email templates unless you install third-party add-ins or integrate your email with a desktop client. Therefore, the browser client works best for those who either don’t need this functionality or plan to utilize third-party tools.
Domain names can be used in a number of ways. Direct visitors to your website’s home page or use complementary domains to send them to specific areas of your website ( e.g. yourcompany.jobs for a careers page). Or, forward a custom domain to an existing social media account, like your Twitter profile or Periscope channel. With a domain name you can even set up custom email addresses like [email protected], which can be used to conduct business or communicate with your followers. More.
Registries and registrars usually charge an annual fee for the service of delegating a domain name to a user and providing a default set of name servers. Often, this transaction is termed a sale or lease of the domain name, and the registrant may sometimes be called an "owner", but no such legal relationship is actually associated with the transaction, only the exclusive right to use the domain name. More correctly, authorized users are known as "registrants" or as "domain holders".
The Choice Plus plan offers the same email functionality as the plus plan along with access to SpamExperts but also includes domain privacy. The plan has an introductory cost of $5.95 per month — matching that of the Plus plan — and a regular price of $14.99 per month. Bluehost gives users secure socket layer (SSL) security for transactions on your website, but some third-party plug-ins can affect the security of your data.
When the Domain Name System was devised in the 1980s, the domain name space was divided into two main groups of domains.[7] The country code top-level domains (ccTLD) were primarily based on the two-character territory codes of ISO-3166 country abbreviations. In addition, a group of seven generic top-level domains (gTLD) was implemented which represented a set of categories of names and multi-organizations.[8] These were the domains gov, edu, com, mil, org, net, and int.
The flip side of that coin is specialization. Many operators believe that hosted email services are useful mainly to companies interested only in general-purpose email use and that any specialized application requires an in-house deployment. This might be true depending on the app but it might not depending on the capabilities offered by the hosted email provider. Email marketing is a great example. Some hosted email providers have special service suites aimed specifically at email marketers, many of whom can send out thousands of emails per month, focused not so much on communication as they are on marketing. These service providers deliver more than just volume, too, as they also offer custom email creation tools and sophisticated marketing and tracking metrics.
Domain names serve to identify Internet resources, such as computers, networks, and services, with a text-based label that is easier to memorize than the numerical addresses used in the Internet protocols. A domain name may represent entire collections of such resources or individual instances. Individual Internet host computers use domain names as host identifiers, also called hostnames. The term hostname is also used for the leaf labels in the domain name system, usually without further subordinate domain name space. Hostnames appear as a component in Uniform Resource Locators (URLs) for Internet resources such as web sites (e.g., en.wikipedia.org).
Examples of this include things such as instant messaging (IM) and team chat tools, video conferencing software, online meeting collaboration tools, shared team intranet sites, and more. Some even integrate with third-party tools such as Slack, a highly popular collaboration tool that combines customizable chat "channels" with file sharing and project management. For those who want to integrate with certain apps more deeply or integrate with custom-developed apps they have built in-house, many bigger-name email services will provide robust application programming interfaces (APIs) that will let your in-house developers or consultants deliver on those needs. They will need to be involved in the email service selection process, however, as this is an important consideration during your evaluation period.
