Who Assigns Ip Addresses-45
A static Internet Protocol (IP) address (static IP address) is a permanent number assigned to a computer by an Internet service provider (ISP).Static IP addresses are useful for gaming, website hosting or Voice over Internet Protocol (Vo IP) services. Because a static address is constant, systems with static IP addresses are vulnerable to data mining and increased security risks.

The addresses are used for network identification and communication. Unlimited IP address requirements were not considered when the Internet was first conceptualized.

At that time, Internet Protocol version 4, based on 32-bit addressing (IPv4) allowed for 4.2 billion unique addresses.

(That's why it's called a router.) Computers on the internal networks, be it Wi-Fi or Ethernet, at home or in the office, have their own IP addresses assigned to them (usually by the router).

That way, all the nodes on the internal network can also communicate.

However, you can set up "static IP addresses" on computers so they never change—this can be important for some kinds of network communications, especially if it's crucial to be able to find that same node over and over.

You could also get a static IP for your router—which is handy if you run a web server, for example, but expect your ISP to charge extra.That's all good to know, but how do you find your IP address?There may come a time when you need to know the IP address of your router, as assigned by your ISP.Even then, ISPs approached static addressing conservatively by limiting static addresses to unused IP addresses to facilitate temporary IP, or dynamic IP, addressing to requesting DHCP servers.With the rapidly expanding use of IP-addressable devices, IPv4's limitations became more apparent.The IPv6 protocol followed IPv4 and provided for 128-bit addressing for virtually unlimited IP addresses.What is the difference between "assigning IP addresses" and "assigning network addresses" procedures?Networks, and the internet, don't identify computers (of any size, even your smartphone) by the name you give them.Computers prefer numbers, and the numbers they use as identifiers are called IP addresses.Continue Reading SFP ports enable Gigabit switches to connect to a wide variety of fiber and Ethernet cables in order to extend switching functionality throughout the...Continue Reading Learn how to understand the difference between bit rate and baud rate in this expert answer.
