Hello, guys! how are you? today's topic will be about 𝐈𝐏 𝐀𝐝𝐝𝐫𝐞𝐬𝐬𝐢𝐧𝐠. you won’t find two computers connected to the internet using the same ip address. but unlike physical addresses, a computer’s ip address is not geographically based or linked. instead, its location is based on a string of numerical digits and dots that are known as an ip address. these ordinal addresses signal to the devices responsible for passing along the information, letting them know two things:
• who is the one sending information?
• to whom are they sending these commands?
an ip address can appear in one of two states, dynamic or static.
• 𝐃𝐲𝐧𝐚𝐦𝐢𝐜 𝐈𝐏 𝐚𝐝𝐝𝐫𝐞𝐬𝐬 – the vast majority of ip addresses most commonly used are in a dynamic state. this means the ip address is neither fixed nor owned; it is temporarily leased out through a leasing system known as the dynamic host configuration protocol (dhcp) and internet service providers. these lease requests and grants happen rapidly, and in an automated fashion, so when one lease expires, your computer instantly requests a new one. although a rare occurrence, if two computers are assigned the same ip address, one connects to a different ip address immediately.
• 𝐒𝐭𝐚𝐭𝐢𝐜 𝐈𝐏 𝐚𝐝𝐝𝐫𝐞𝐬𝐬 – a static address can only be given by configuring and editing your computer’s network settings. this is not a common method and is only advised for people well versed in tcp and ip.
there are currently two version of internet protocol (ip): 𝐈𝐏𝐯𝟒 and a new version called 𝐈𝐏𝐯𝟔.
𝐓𝐡𝐞 𝐈𝐏𝐯𝟒 𝐚𝐝𝐝𝐫𝐞𝐬𝐬 is a 32-bit number that uniquely identifies a network interface on a machine. an ipv4 address is typically written in decimal digits, formatted as four 8-bit fields that are separated by periods. each 8-bit field represents a byte of the ipv4 address. this form of representing the bytes of an ipv4 address is often referred to as the 𝐝𝐨𝐭𝐭𝐞𝐝-𝐝𝐞𝐜𝐢𝐦𝐚𝐥 𝐟𝐨𝐫𝐦𝐚𝐭.
the bytes of the ipv4 address are further classified into two parts: the 𝐧𝐞𝐭𝐰𝐨𝐫𝐤 𝐩𝐚𝐫𝐭 and the 𝐡𝐨𝐬𝐭 𝐩𝐚𝐫𝐭.
