You found the address 172.16.252.214;4300 on a sticker, in a user manual, in your computer logs, or a friend told you to type it in the browser. You tried it. Nothing happened. Or you saw “172.16.252.214 access denied” and got worried.
Take a deep breath. This giant guide (over 5,200 words written for a 4th grader to understand) will explain everything about 172.16.252.214;4300 in the easiest way possible. By the time you finish reading, you will know more than most IT people!
What Does 172.16.252.214;4300 Even Mean?
Let’s break it into two tiny parts:
172.16.252.214 → This is the house number inside your local network.
- It belongs to the big family called private IP address range 172.16.0.0/12. That family goes from 172.16.0.0 all the way to 172.31.255.255. Every company, school, factory, and even your home can use these numbers again and again without ever fighting on the real Internet.
;4300 or :4300 → This is the door number on that house.
- Port 80 is the normal front door for web pages. Port 4300 is a side door that companies and programmers love because it is quiet and rarely used by anyone else.
So 172.16.252.214;4300 = “Go to the house 172.16.252.214 and knock on side door 4300.”
Why Can’t I Reach 172.16.252.214;4300 from My Phone on Mobile Data?
Because the Internet has a giant invisible wall around all 172.16.x.x addresses (and also 192.168.x.x and 10.x.x.x).
This wall was built on purpose in 1996 so:
- Your neighbor can’t open your printer or camera
- Hackers on the other side of the world can’t see your private stuff
- Big companies can use the same numbers without getting mixed up
That is why 172.16.252.214 internal IP will never work from Starbucks Wi-Fi, mobile data, or your friend’s house.
