Next are third-level domains, which are written immediately to the left of a second-level domain. There can be fourth- and fifth-level domains, and so on, with virtually no limitation. An example of an operational domain name with four levels of domain labels is sos.state.oh.us. Each label is separated by a full stop (dot). 'sos' is said to be a sub-domain of 'state.oh.us', and 'state' a sub-domain of 'oh.us', etc. In general, subdomains are domains subordinate to their parent domain. An example of very deep levels of subdomain ordering are the IPv6 reverse resolution DNS zones, e.g., 126.96.36.199.0.0.0.0.0.0.0.0.0.0.0.0.0.0.0.0.0.0.0.0.0.0.0.0.0.0.0.0.ip6.arpa, which is the reverse DNS resolution domain name for the IP address of a loopback interface, or the localhost name.
Make sure your Internet service contract allows hosting. Many Internet service providers (ISPs) expressly forbid personal hosting unless you have a business plan, which often costs significantly more than a standard use plan. This shouldn't be an issue if your site only generates a few hits per month, but any kind of significant traffic will draw attention to your hosting.
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".
VPS Hosting: A virtual private server (VPS) setup is like a shared hosting setup on steroids. It generally uses more powerful hardware and takes its name from the fact that while multiple websites are being stored on the same physical hardware, each uses virtualisation software to allow them to operate independently as though they were dedicated mini-servers.
For the more enterprise-oriented customers, they offer a full range of VPS and cloud hosting, along with serious Java Tomcat hosting, including shared and private JVMs, as well as Java VPS offerings. With a company named MochaHost, you'd expect some quality Java support and they have it. So brew yourself a cuppa, open a browser window, and give MochaHost a spin. You have half a year to make up your mind, so if it turns out MochaHost really isn't your cup of tea, they'll understand.
Many services offer so-called unlimited or unmetered service for whatever amount of bandwidth, disk storage and sites you use. It's important to understand that most terms of service actually do limit the definition of "unlimited" to what's considered reasonable use. The bottom line is simple: if you're building a pretty basic website, unlimited means you don't need to worry. But if you're trying to do something excessive (or illegal, immoral or fattening), the fine print in the terms of service will trigger, and you'll either be asked to spend more or go elsewhere.
