What Is an IP Address?
Now, if you're in the dark about what an IP address actually is, this is all nonsense to you. If that's the case, let me fill in the gaps. It's all a numbers game. An IP address (the IPv4 version, which is the most common) consists of a string of numbers, separated by periods (dots). Each IP address is separated into four segments by three periods. Jan 15, 2019 · The IP address, or the Internet Protocol, is a string of numbers assigned to your device so you can connect to the internet. An IP address is easiest explained with the following example. When you're online shopping, the delivery guy needs your address to get the package to your house. Same goes when connecting to the internet. May 15, 2020 · Where the value of a,b,c or d is between 0-255 decimal. A typical IP address appears like this: 192.168.0.1. Networks and Nodes. An IP address has two components- A network component, and a node component. As an Analogy if you think of the address of your house it is of the form. House Number + Street name e.g 12 King Street. Class B IP address always has its first bits as 10, next 14 bits as a network address and following 16 bits as the host address. The range of IP addresses is 128.0.0.0 to 191.255.255.255. This means that it allows 2^14 networks and 2^16 hosts per network. This class of IP address is used for a medium network like multinational companies. Class
Because of this arrangement, each DNS server maintains only a small portion of the total DNS host to IP address mappings. The collection of host-name-to-IP-address mappings contained with the DNS database is also known as a namespace. Essentially, when looking for a name in DNS, the DNS client first checks a top-level DNS server database.
Understand IP Addresses An IP address is an address used in order to uniquely identify a device on an IP network. The address is made up of 32 binary bits, which can be divisible into a network portion and host portion with the help of a subnet mask. The 32 binary bits are broken into four octets (1 octet = 8 bits). On a particular machine, a port number coupled with the IP address of the machine is known as a socket. A combination of IP and port on both client and server is known as four tuple. This four tuple uniquely identifies a connection. In this section we will discuss how port numbers are chosen. Dynamic IP addresses are issued using a leasing system, meaning that the IP address is only active for a limited time. If the lease expires, the computer will automatically request a new lease. Sometimes, this means the computer will get a new IP address, too, especially if the computer was unplugged from the network between leases. Mar 12, 2014 · For example, we could express the idea that the IP address 192.168.0.15 is associated with the netmask 255.255.255.0 by using the CIDR notation of 192.168.0.15/24. This means that the first 24 bits of the IP address given are considered significant for the network routing. This allows us some interesting possibilities.
One other important protocol in the TCP/IP site is User Datagram Protocol (UDP).This protocol is basically a scaled-down version of TCP. Just like TCP, this protocol provides delivery of data between applications running on hosts on a TCP/IP network, but, unlike TCP, it does not sequence the data and does not care about the order in which the segments arrive at the destination.

IP Address: A logical numeric address that is assigned to every single computer, printer, switch, router or any other device that is part of a TCP/IP-based network Subnet : A separate and identifiable portion of an organization's network, typically arranged on one floor, building or geographical location Jul 05, 2017 · IP sharing: Your ISP assigns you one IP address. If you have a desktop, a laptop, a media box on your TV, and an iPad, that one IP address clearly isn’t going to cut it. A router manages those multiple connections and ensures that the right packets of information go to the right places.
