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., 1.0.0.0.0.0.0.0.0.0.0.0.0.0.0.0.0.0.0.0.0.0.0.0.0.0.0.0.0.0.0.0.ip6.arpa, which is the reverse DNS resolution domain name for the IP address of a loopback interface, or the localhost name.
ImageShack has a great interface that showcases its best photos in a layout similar to Pinterest’s. You have to create an account to upload photos, but the free account offers many helpful features. You can organize your photos into albums, and you can add tags to keep track of your images and let other users discover your work. If you don’t want the ImageShack community to view your photos, you can keep your images private or only share them with a selected audience.

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.


Unlike shared or VPS hosting, dedicated hosting makes your website the lone tenant on a server. To extend the housing metaphor, having a dedicated server is like owning your own home. The means that your website taps the server's full power, and pays for the privilege. If you're looking for a high-powered site—an online mansion for your business—dedicated hosting is the way to go. That said, many dedicated web hosting services task you with handling backend, technical issues, much as homeowners have manage maintenance that renters generally leave to their landlords.

Early image and data storage servers also initially left the uploaded content unchanged, sometimes resulting in undesirable web page display problems, such as too high resolution causing page layout problems in discussion forums, or too high detail causing very slow page loading times. The sharing of potentially incompatible image formats could also result in them not displaying properly for some viewers.
Another top site for easily sharing photos, Free Image Hosting is similar to Imgur but without the trendy layout and or the convenient hyperlink shortener. As long as you don't mind the ads all over the site, you can upload images without needing to create a free account first and Free Image Hosting provides you with the HTML code to a direct link to your photo so you can share it easily.
Name servers. Most registrars provide two or more name servers as part of the registration service. However, a registrant may specify its own authoritative name servers to host a domain's resource records. The registrar's policies govern the number of servers and the type of server information required. Some providers require a hostname and the corresponding IP address or just the hostname, which must be resolvable either in the new domain, or exist elsewhere. Based on traditional requirements (RFC 1034), typically a minimum of two servers is required.

One of the primary new features of the early and developing Web that enabled the easy sharing of images and other data, was the concept of being able to upload or HTTP POST a file via the web browser to the remote server. This alone helped to eliminate all the complex steps of needing to understand command line tools like FTP or uploading via a modem terminal.
TinyPic is owned by Photobucket, so it offers many of the same features. However, you don’t need to create an account to upload photos, so you can quickly and easily upload a photo for sharing. To upload a photo, you simply select the image, add tags if you want to, and set the size of the photo. You’ll get a link that you can use to share a photo anywhere. The optional tags will allow TinyPic users to find your photos through a search. 

A web service is any piece of software that makes itself available over the internet and uses a standardized XML messaging system. XML is used to encode all communications to a web service. For example, a client invokes a web service by sending an XML message, then waits for a corresponding XML response. As all communication is in XML, web services are not tied to any one operating system or programming language—Java can talk with Perl; Windows applications can talk with Unix applications.
Intercapping is often used to emphasize the meaning of a domain name, because DNS names are not case-sensitive. Some names may be misinterpreted in certain uses of capitalization. For example: Who Represents, a database of artists and agents, chose whorepresents.com[23], which can be misread. In such situations, the proper meaning may be clarified by placement of hyphens when registering a domain name. For instance, Experts Exchange, a programmers' discussion site, used expertsexchange.com, but changed its domain name to experts-exchange.com.[24]
