Have you ever typed an IP address and gotten an error? The string 111.90.150.2404 might look like a valid address, but it is not. The last number, 2404, exceeds the maximum allowed value of 255 for any octet in an IPv4 address.
Why Users Encounter This Invalid Address and Its Real-World Impact
People often encounter 111.90.150.2404 when copying or typing IP addresses from memory. A simple extra digit can break connectivity. For network administrators, such typos cause confusion and wasted time troubleshooting. Users may think their internet is down when the real issue is a mistyped address. The invalid string has no official assignment, so any attempt to connect to it fails immediately. This highlights the importance of double-checking numerical entries in network settings.

How IP Addresses Are Structured and Where the Error Occurs
IPv4 addresses consist of four numbers separated by periods, each ranging from 0 to 255. The address 111.90.150.2404 violates this rule because 2404 is far above 255. The intended address was likely 111.90.150.240, which falls within a block assigned to Malaysia’s TM Net ISP. The extra digit 4 at the end is a common typographical error. Understanding the structure helps users identify such mistakes quickly. Network tools often reject invalid addresses outright, preventing accidental misuse.
Timeline of Key Moments in IP Addressing and This Specific Error
The IPv4 standard was established in 1981, defining the 0-255 range per octet. Since then, billions of addresses have been assigned. The specific string 111.90.150.2404 has no recorded history because it never existed as a valid address. However, the block 111.90.150.0/24 was allocated to TM Net in Malaysia years ago. The typo likely emerged from user error in forums or configuration files. No official events or releases are tied to this invalid string.
Regional Relevance and How Malaysian Users Are Affected
Since the valid address 111.90.150.240 belongs to Malaysia’s TM Net, users in Malaysia may encounter the typo more often. Local internet forums sometimes discuss connection issues caused by mistyping this address. The error is not unique to Malaysia, but the regional ISP association makes it a common point of confusion there. Understanding the correct format helps Malaysian users avoid unnecessary support calls. The broader lesson applies globally: always verify IP addresses before use.
| Component | Valid Range | Example |
|---|---|---|
| First Octet | 0–255 | 111 |
| Second Octet | 0–255 | 90 |
| Third Octet | 0–255 | 150 |
| Fourth Octet | 0–255 | 240 (not 2404) |
Frequently Asked Questions
How does 111.90.150.2404 differ from a valid IP address?
A valid IPv4 address has four octets each between 0 and 255. The string 111.90.150.2404 has a fourth octet of 2404, which exceeds the maximum, making it invalid. The intended address was likely 111.90.150.240.
How many octets are in an IPv4 address?
An IPv4 address contains four octets, each represented by a decimal number from 0 to 255. The octets are separated by periods. This format allows for over 4 billion unique addresses.
Who is responsible for assigning IP addresses like 111.90.150.240?
IP addresses are assigned by regional internet registries. The block containing 111.90.150.240 is managed by the Asia Pacific Network Information Centre (APNIC) and allocated to Malaysia’s TM Net ISP.
When did the IPv4 standard establish the 0-255 range?
The IPv4 standard was defined in RFC 791 in September 1981. It specified the 32-bit address format with four octets, each ranging from 0 to 255. This standard remains in use today.
What is 111.90.150.2404 best known for?
111.90.150.2404 is best known as a common typographical error. It appears in online discussions and configuration files as a mistake for the valid address 111.90.150.240. It serves as a cautionary example of how small typos can cause network issues.
Common Misconceptions About Invalid IP Addresses
Some users believe that adding extra digits to an IP address might still work if the number is within a certain range. This is false. The IPv4 protocol strictly enforces the 0-255 limit per octet. Even a single digit beyond that makes the address unusable. Another misconception is that such errors are harmless. In reality, they can cause application crashes or infinite loading loops when software attempts to parse the malformed string.
How to Verify and Correct IP Address Entries
When you encounter an error with an IP address, the first step is to check each octet. Ensure no octet exceeds 255. For the string 111.90.150.2404, simply remove the trailing 4 to get 111.90.150.240. Many online tools can validate IP addresses instantly. Network administrators should implement input validation to catch such typos early. Educating users about the correct format reduces support tickets and downtime.
Security Implications of Mistyped IP Addresses
While 111.90.150.2404 itself is harmless, similar typos can lead to security risks. A mistyped address might accidentally point to a different server, potentially exposing sensitive data. This practice, known as typosquatting, exploits user errors. Although the invalid string in question cannot be hijacked, the habit of verifying addresses protects against such threats. Always double-check before entering IPs in security-critical contexts.
Tools and Techniques for Avoiding IP Typos
Several tools help users avoid mistakes like 111.90.150.2404. Ping and traceroute commands reject invalid addresses immediately. Browser address bars also flag malformed entries. For frequent network work, consider using a subnet calculator or IP validator. Copy-pasting from reliable sources reduces errors. Some operating systems offer autocomplete for known addresses. Training staff on IP basics prevents many common typos. A few seconds of verification can save hours of troubleshooting.
