Understanding IP Addressing


Every computer that communicates over the Internet is assigned an IP address that uniquely identifies the device and distinguishes it from other computers on the Internet.
(IP Address)

What is an IP Address?


An IP address is an identifier for a computer or device on a TCP/IP network. Networks using the TCP/IP protocol route messages based on the IP address of the destination.

An IP address consists of 32 bits, often shown as 4 octets of numbers from 0-255 represented in decimal form instead of binary form. For example, the IP address: 168.212.226.204 in binary form is 10101000.11010100.11100010.11001100.

But it is easier for us to remember decimals than it is to remember binary numbers, so we use decimals to represent the IP addresses when describing them. However, the binary number is important because
that will determine which class of network the IP address belongs to.

What is an IP address?

Every device connected to the public Internet is assigned a unique number known as an Internet Protocol (IP) address. IP addresses consist of four numbers separated by periods (also called a 'dotted-quad') and look something like 127.0.0.1.

Since these numbers are usually assigned to internet service providers within region-based blocks, an IP address can often be used to identify the region or country from which a computer is connecting to the Internet. An IP address can sometimes be used to show the user's general location.

Because the numbers may be tedious to deal with, an IP address may also be assigned to a Host name, which is sometimes easier to remember. Hostnames may be looked up to find IP addresses, and vice-versa. At one time ISPs issued one IP address to each user. These are called static IP addresses. Because there is a limited number of IP addresses and with increased usage of the internet ISPs now issue IP addresses in a dynamic fashion out of a pool of IP addresses (Using DHCP). These are referred to as dynamic IP addresses. This also limits the ability of the user to host websites, mail servers, ftp servers, etc. In addition to users connecting to the internet, with virtual hosting, a single machine can act like multiple machines (with multiple domain names and IP addresses).

Was ist eine IP-Adresse?

Jedes Gerät, dass zum Internet verbunden ist, hat eine eindeutige Nummer zugewiesen, bekannt als Internet Protocol Adress (IP). IP Adressen bestehen aus vier Nummern, die durch Punkte (auch genannt "Dotted-Quad") getrennt werden. Eine Adresse kann so aussehen: 127.0.0.1.

Seitdem diese Nummern normalerweise einem Provider zugeordnet werden, der diesen Regionen zuteilt, kann eine IP Adresse dazu benutzt werden, die Region oder das Land herauszufinden, von dem ein Computer sich zum Internet verbindet. Manchmal kann eine IP Adresse sogar benutzt werden, um die exakte des Computers zu zeigen.

Weil es schwer ist, sich an solche Nummern zu erinnern, können IP Adressen einem Host Namen zugeordnet werden, an den man sich leichter erinnert. Host Namen können dazu verwendet werden IP Adressen zu finden und umgekehrt. Einst vergaben Provider IP Adressen an jeden Benutzer. Diese nennt man statische IP Adressen. Weil es nur eine begrenzte Anzahl an an IP Adressen gibt und da die Vergabe von IP Adressen stetig ansteigt, vergeben die Provider jetzt in einer dynamischen Art Adressen aus einer Gruppe von IP Adressen heraus (mittels DHCP). Diese bezeichnet man als dynamische IP Adressen. Das begrenzt allerdings auch die Fähigkeiten eines Nutzers Webseiten, Mail Server, FTP Server und andere zu hosten. Zusätzlich zu Nutzern die sich zum Internet verbinden, kann mit virtuellem Hosting eine einziger Rechner wie mehrere Rechner zusammen auftreten (Mit verschiedenen Domains, Namen und IP Adressen).

How do I change my IP address?

"How do I change my IP address?" and "Can I change my IP address?" are probably the most commonly asked questions. Please attempt the following then, if that does not work, visit the Change IP Address forum.

Before trying any other methods to change your IP address, try turning off (or unplugging the power of) your Cable/DSL modem for five minutes. In many cases this will change your IP address. However, if that does not change your IP address, repeat the process for 8 hours (overnight works well) instead of 5 minutes. Hopefully this will result in an IP change.

If the above does not result in your IP address changing, please look through the below for the situation that best matches yours and attempt to change your IP address that way. Unfortunately you are not able to get your IP address to change in all cases, as it is ultimately determined by your ISP's DHCP configuration (when you've got a dynamically assigned IP address, that is.)
