At first glance, it looks like an IP address, but a closer inspection reveals that it does not follow standard IPv4 or IPv6 formatting rules.
This article provides a complete, -friendly, and technically accurate explanation of 111.90.150.402r, including what it may represent, why it appears in logs or searches, whether it poses a security risk, and how website owners and users should respond.
Understanding the Structure of 111.90.150.402r
To understand 111.90.150.402r, it’s important to break it down structurally.
A standard IPv4 address consists of four numbers (octets), each ranging from 0 to 255, separated by dots. For example:
- 192.168.1.1
- 8.8.8.8
However, 111.90.150.402r includes:
- A number greater than 255 (
402) - A trailing alphabetic character (
r)
This immediately confirms that 111.90.150402r is not a valid IP address under standard internet protocols.
Is 111.90.150.402r a Real IP Address?
No, 111.90.150.402r is not a valid IP address.
Here’s why:
- IPv4 octets cannot exceed 255
- IP addresses cannot include letters
- The suffix “r” invalidates it as a network identifier
This means 111.90.150.402r is either:
- A malformed or mistyped IP
- A bot-generated string
- A tracking or logging artifact
- A fake identifier used in scanning attempts
