Question: What Are The 4 Parts Of An IP Address?

What are different types of IP addresses?

There are four different types of IP addresses: public, private, static, and dynamic.

While the public and private are indicative of the location of the network—private being used inside a network while the public is used outside of a network—static and dynamic indicate permanency..

What are the 4 parts of an IP address called?

IPv4 addresses are usually represented in dot-decimal notation, consisting of four decimal numbers, each ranging from 0 to 255, separated by dots, e.g., 172.16. 254.1. Each part represents a group of 8 bits (an octet) of the address.

What is the After an IP address?

The slash following the IP address is the abbreviation for the subnet mask. … The amount of ones in the subnet mask is equal to the number of the abbreviation. For example, the /16 subnet mask you asked about would have 16 ones in a row, the rest of the numbers being zeros. 11111111.11111111.

How do you classify an IP address?

Network Administration: Classifying IP AddressesIf the first bit is zero, the address is a Class A address.If the first bit is one and if the second bit is zero, the address is a Class B address.If the first two bits are both one and if the third bit is zero, the address is a Class C address.More items…

What is the first IP in a subnet called?

network addressWithin a subnet, the first and last IP addresses are only used to a limited extent. The first IP address (this has only zeros in the host part) is called the network address. This means that there are always two hosts less than addresses available.

What does each section of an IP address mean?

Each 8-bit field represents a byte of the IP address. … This form of representing the bytes of an IP address is often referred to as the dotted-decimal format. The bytes of the IP address are further classified into two parts: the network part and the host part.

What is a 192.168 IP address?

Using 192.168. 192.168. 0.0 is the beginning of the private IP address range that includes all IP addresses through 192.168. … One common IP address assigned to home routers is 192.168. 1.1. This IP address is used because the router is on the 192.168.

How can I see my IP address?

Or you can go full geek and open the Terminal and type “ipconfig” just like on Windows. On an iPhone, go into Settings > Wi-Fi, and click the “i” in a circle () next to the network you’re on. The IP address, subnet, and router (gateway) will all be there under the DHCP tab.

How many IP addresses are there?

4,294,967,296 IPv4 addressesThe two most common versions of IP in use today are Internet Protocol version 4 (IPv4) and Internet Protocol version 6 (IPv6). Both IPv4 and IPv6 addresses come from finite pools of numbers. For IPv4, this pool is 32-bits (232) in size and contains 4,294,967,296 IPv4 addresses.

How do IP subnets work?

A subnet mask is used to divide an IP address into two parts. One part identifies the host (computer), the other part identifies the network to which it belongs. To better understand how IP addresses and subnet masks work, look at an IP (Internet Protocol) address and see how it is organized.

What does 16 mean in IP address?

Each number between the dots in an IP address is actually 8 binary digits (00000000 to 11111111): we write them in decimal form to make it more readable for humans. The `/16′ means that the first 16 binary digits is the network address, in other words, the `1.2.

What is a public IP address?

A public IP address is an IP address that can be accessed over the Internet. Like postal address used to deliver a postal mail to your home, a public IP address is the globally unique IP address assigned to a computing device.

What is IP loopback address?

A loopback address is a special IP address, 127.0. 0.1, reserved by InterNIC for use in testing network cards. This IP address corresponds to the software loopback interface of the network card, which does not have hardware associated with it, and does not require a physical connection to a network.

What are the 3 major classes of an IP network?

Currently there are three classes of TCP/IP networks. Each class uses the 32-bit IP address space differently, providing more or fewer bits for the network part of the address. These classes are class A, class B, and class C.

What is the 3rd octet of an IP address?

A Class B address has the first and second octets as the network portion and the third and fourth octets as the host portion. A Class B network mask is shown as 255.255. 0.0. A Class C address has the first, second, and third octet as the network portion and the last octet as the host portion.
