What is a domain?

They would like to have your own domain, but do not know exactly how this all about? Or do you have one (congratulations!) And want to know what that has to do with emails and how to create a website? This blog is dedicated to exactly this topic.

So, all the world speaks of "www.irgendwas.de", e-mail addresses and Web sites.

Any e-mail address you get virtually anywhere through mass merchandisers for little to no money. This allows you to send and receive email, save to a limited extent. Disadvantage: These e-mail addresses, each - recognizable by the symbol of the supplier on the right side of the "@". This e-mail addresses do not act very professional in the business field. But for simple personal use them rich natural. (However, one often very little to no customization of e-mails.:-()

If you want to present his business online and fittingly "represent", then you should do it on their own website.

A website has ugs a "domain", more precisely, a URL (Uniform Resource Locator), under which one can reach them;. for example, we here just onsite.org (here in Germany reached the most .de, the country code for Germany. But there are many more, some with restricted access). This "domain" is practically the address on the Internet. Behind this lies a number line with the "address" of the server on which the content of the website is stored.

Constructed is the domain name or "domain" from right to left. On the far right is the TLD, that is, Top-level domain; either a "geographical" (.de, .at, .ch, etc.) or a "generic" suffix (.com, .net, .mobi, etc.). To the left is the second level domain (eg "meine-firma.de"). Has anyone else can register the domain that you want yourself, there is still the possibility of obtaining by minor variations similar free domain. (Try our domain and check domain Finder!)

Own domains or domains can be from different providers, so-called. Register "registrars".

In the next step you worried memory on a so-called. Webserver. A web server is a computer that is accessible from the Internet, in principle. Normally, the average consumer does not have a server are at home with you, but to book as much server space as you need with a provider (eg onsite;-)).

About this server space you can then send and receive e-mails. If you have your own domain, for example, "Www.irgendwas.com" or "fritzchenmueller.de", you can also create attractive e-mail addresses: The Domain fritzchenmueller.de could, for example, post@fritzchenmueller.de the address or buchhaltung@fritzchenmueller.de etc. set up. Let's be honest: Would you rather shop at an anonymous "firma12345@xyz.de" or a personal "info@meinefirma.de" ???

In addition to e-mail you can of course also run a website with its own domain. With an appropriate program (for some of our packages include free, see webseiten-gestaltung.eu) eg writes and / or one designed his text, image and / or sound (or, if you have no time or is not so computer savvy, can be programmed, eg by us;-)). Then everything is also stored on the web server. Now you can access it from all over the world, to the content stored there and look at (and possibly listen) what is offered everything there.

So, that was more than enough for a blog - soon it continues with special applications on your website, for example, own online store or even online auctions.

If you want to know more about domains in the meantime, HTML, etc. Webspace: Just browse through our website; next to our domain, web space and web design offer also includes extensive FAQ pages and small free tools.

Dynamic Host Configuration Protocol (DHCP)

DHCP (Dynamic Host Configuration Protocol) simplifies the assignment of IP addresses on a network. What is needed is to at least one DHCP server. Distributes IP addresses to the different clients.

On the server side, an address space is defined. IP addresses from this pool are allocated to the clients when they ask the DHCP server for it. For this to happen, the network configuration of the client must be set accordingly. This is now standard on operating systems such as Linux and Windows is the case, so that an administrator does not have to worry about the settings of the client.

A DHCP server automatically, manually or dynamically assigns IP addresses. Automatically addresses can be assigned only once. It receives a client that is identified by the MAC address of its network interface, at first logon the network a free IP address. Which is bound to the MAC address, and the client gets it in the future at each login. In contrast, dynamically distributed IP addresses are cashed by the server after a certain time.

The latter method should always be used in the larger network, otherwise the IP addresses could be almost there. Caution: This can happen even in smaller networks, if one uses often times virtual environments such as VMware Workstation, Parallels Desktop or Citrix XenServer. These generate multiple virtual network interfaces depending on configuration. The most cumbersome method, but certainly is used, is the manual assignment of IP addresses. Here you can assign a specific address one or more clients an administrator - such as a router or a network printer.

The request from the client by means of broadcast. Thus, to test how many DHCP servers exist on the network. The contacted server is sent in response a suggested configuration. If the client accepts this, it sends a DHCP request (DHCP request). The server in turn sends the IP address and the required parameters. At the end of the session, the client sends a release back to the server and reports so that the IP address is no longer needed (DHCP Release).
