What is an IP address?
An IP address, short for 'Internet Protocol Address,' is a numerical label used to identify every device on the internet. If you imagine the internet as a huge city, then every connected device—whether it's a phone, computer, or router—is like a building in that city, and the IP address is its house number. Every device connected to the internet must have an IP address.
IPv4 and IPv6
IP addresses are mainly divided into two types: IPv4 and IPv6. IPv4 stands for Internet Protocol version 4 and is one of the most widely used protocols on the internet today. An IPv4 address consists of 32 binary bits, usually represented as four groups of numbers between 0 and 255, such as 192.168.1.1 or 134.152.68.62. IPv4 can represent a total of about 4.2 billion addresses. However, with the global population now exceeding 7 billion and the number of connected devices far surpassing that, the number of IPv4 addresses is no longer sufficient to meet the demand for assigning a unique IP address to every device.
To address the problem of IPv4 address exhaustion, IPv6 was created. An IPv6 address is composed of 128 bits, divided into 8 groups, with each group consisting of 4 characters from 0 to 9 or A to F. The number of addresses IPv6 can provide is as high as 2 to the power of 128—an astronomical figure. To put it in perspective: we could assign an IPv6 address to every grain of sand on Earth.
Because IPv6 requires support from Internet Service Provider (ISP) equipment, we rarely encounter IPv6 addresses in daily use. If you see an IPv6 address for the first time, don't be surprised and think your IP address has turned into gibberish—it just means your ISP has assigned you an IPv6 address, and you can still browse the internet normally.
Geolocation, Time Zone, and Local Time
IP addresses are like phone numbers; different countries and regions have different address ranges. Therefore, some organizations and companies maintain vast IP address databases that record the geographical location information corresponding to each IP address—these are known as IP geolocation databases. Using these databases, you can look up the geographical location of a specific IP address.
For example, using the IP lookup tool on realfp.com, you can determine the country or region to which an IP address belongs. The IP address 23.249.18.125 is located in Hong Kong. With other tools, you can also obtain the approximate geographic coordinates—latitude and longitude—of an IP address.
Summary
In summary, through an IP address, a website can learn various pieces of information about its visitors, including their geographical location, time zone, and more. The IP address is the foundation of internet communication and a crucial basis for websites to identify and analyze their visitors.
