A few companies have offered low-cost, below-cost or even free domain registration with a variety of models adopted to recoup the costs to the provider. These usually require that domains be hosted on their website within a framework or portal that includes advertising wrapped around the domain holder's content, revenue from which allows the provider to recoup the costs. Domain registrations were free of charge when the DNS was new. A domain holder may provide infinite number of subdomains in their domain. For example, the owner of example.org could provide subdomains such as foo.example.org and foo.bar.example.org to interested parties.
A fully qualified domain name (FQDN) is a domain name that is completely specified with all labels in the hierarchy of the DNS, having no parts omitted. Labels in the Domain Name System are case-insensitive, and may therefore be written in any desired capitalization method, but most commonly domain names are written in lowercase in technical contexts.
People use websites for all kinds of things, and exactly what you want to do will dictate what kind of web hosting you need. In addition to the types of web hosting we covered in the previous section, which can generally be used for many different types of websites, there are specialty options that cater to a specific subset of users. We will cover these options below.
For example, you may certainly contact your host at any time, but when are they available to respond to your questions and concerns? How long will it take for someone to get back to you? Will there be someone to help you if your mission-critical website goes down at 3:00 in the morning? What language(s) do your host providers speak? Support in Malagasy is probably essential if you live and work in Madagascar, but fairly useless if you are in North America.
Shared web hosting is the most affordable type of domain hosting available. Its affordability is due to the fact that you share a server with various companies who also want a low-cost web hosting plan. Each company that shares this server has its own specified amount of storage space that is defined by the hosting package Depending on the size of the server, you could possibly have thousands of websites hosted on the same platform, with each user receiving an allotment of the total available bandwidth, memory, and power.
Unlike VPS hosting, which is limited by the physical server on which your website is hosted, cloud hosting allows you to use resources offered by multiple machines. For example, if you find that your website is lagging because of lack of bandwidth, you can increase the amount available to you. Often, you can make this change yourself via the host's control panel.
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.
For packages supporting unmetered disk space or data transfer (bandwidth), we do not have defined limitations. These resources are "unmetered", meaning you are not billed according to the amount of disk space or bandwidth used. While of course these resources are not infinite, we believe our customers should have all the resources necessary to build an online presence and 99.95% of customers will have more than enough disk space and bandwidth to meet their needs.
The right to use a domain name is delegated by domain name registrars, which are accredited by the Internet Corporation for Assigned Names and Numbers (ICANN), the organization charged with overseeing the name and number systems of the Internet. In addition to ICANN, each top-level domain (TLD) is maintained and serviced technically by an administrative organization operating a registry. A registry is responsible for maintaining the database of names registered within the TLD it administers. The registry receives registration information from each domain name registrar authorized to assign names in the corresponding TLD and publishes the information using a special service, the WHOIS protocol.
If you aim to have a web presence, you've got to have email. It's a convenient way for potential customers and clients to send you a message, Word document, or other files. Thankfully, most web hosts include email in the price of their hosting plans. Some web hosts offer unlimited email account creation (which is great for future growth), while others offer a finite amount. You, naturally, should want unlimited email.
A domain must be unique (for example there can only be one single Yahoo.com) and must be registered with a domain registrar (ie. NameCheap); while for sub domains, users can freely add it on top of the existing domain as long as their web host provide the service. Some would say sub-domains are the ‘third level’ domains in the sense that they are simply “sub folders” under the domain root directory, normally used to organize your website content in different languages or different categories.
You could think of the sites that share your server as your roommates; there's really not that much separating you from them. Sure, you can close the bedroom door, but they can still cause nightmares for you in the kitchen and the bathroom. In web hosting terms, all the sites share a single server's resources, so huge traffic spike on Site A may impact the neighboring sites' performances. It's even possible that another site could take down the shared server altogether, if it crashed hard enough.
VPS is an abbreviation of Virtual Private Server. This type of web hosting plan is more expensive than shared hosting but still cheaper than dedicated hosting. With VPS, some of the resources are communal, but not all. Memory and CPU time are shared amongst those on the server, but certain shares of said resources are allotted to each domain. This gives you greater computing power or flexibility in the case of traffic surges.
HostGator gained points for uptime monitoring and regular backups, along with free cPanel or Plesk. We liked that SSH is available for the more technically inclined site operators and that dedicated IP addresses could be purchased. We did take points off because it's sometimes difficult to tell what the price is once promotional plans run their course. That said, with a generous 45-day money back guarantee, there's a solution for almost everyone at HostGator.
