111.150.90.2004 is not a valid IPv4 address, so it cannot be looked up for real location or network details.
The number format “111.150.90.2004” breaks the standard rules for IPv4, so no meaningful geolocation or internet registry data exists for it.
What an IP Address Is
An Internet Protocol address, or IP address, is a set of numbers that identifies a device on a network or the internet. Most devices use IPv4 addresses. These appear as four numbers separated by dots, like 111.90.150.204. Each number must be between 0 and 255. If any number is outside this range, the address is invalid and cannot be used for network communication.
Every valid IP address has two main roles:
- It identifies the network location of a device.
- It lets devices send and receive data across the internet or local networks.
Tools called IP lookup or geolocation services use databases to match an IP address to information like country, city, and the internet service provider (ISP).
Why 111.150.90.2004 Is Invalid
A correct IPv4 address must meet these rules:
- It contains four sets of numbers separated by dots.
- Each number is called an “octet.”
- Each octet must be between
0and255.
In the term 111.150.90.2004, the final block 2004 is greater than 255. This makes it an invalid IPv4 address. Because of this, no registry or geolocation system can map it to a real host, ISP, or location.
In short:
| Term | Validity |
|---|---|
| 111.150.90.204 | Valid IPv4 |
| 111.150.90.2004 | Invalid IPv4 |
| Reason | Last octet exceeds 255 |
This means the number might be a typo for a real IP. For example, a similar valid address would be 111.150.90.204. Only valid addresses like that can be looked up for details.
How IP Lookup Works
IP lookup tools collect information from global IP databases. These databases are regularly updated with records from regional internet registries. When you enter a valid IP, the tool returns:
- Country and region
- City (approximate location)
- ISP or organization
- Hostname or network name
- Timezone information
- Latitude and longitude (approximate)
The accuracy of location data depends on the database. City-level information might not always be precise. This is normal because IP addresses are assigned to ISPs or data centers, and not to physical street addresses.
Common IP Lookup Results Explained
Below is an example of real IP lookup data for a valid IPv4 address. This helps you understand what information is possible to find when the IP format is correct.
| Field | Example Value |
|---|---|
| IP Address | 115.186.151.103 |
| Country | Pakistan |
| Region | Islamabad |
| City | Islamabad |
| ISP | Nayatel (Pvt) Ltd |
| Timezone | Asia/Karachi (UTC +5) |
| Hostname | Same as IP |
| Connection Type | cable or DSL |
In this example:
- The address is valid as each number is within 0‑255.
- The lookup shows the ISP and approximate city.
- Tools use pooled databases to match such values.
Why Valid IP Addresses Matter
A valid IP address is necessary for:
- Internet routing and data delivery.
- Geolocation and network analysis.
- Security logging and troubleshooting.
If an IP is invalid, like the string in question, none of these functions work. Any lookup tool will either return no results or reject the input.
IP Address Standards
IPv4 and IPv6 are two standards in use today.
IPv4
- It uses four octets.
- Each octet is from 0 to 255.
- Total unique addresses are about 4.3 billion.
- Format example:
111.90.150.204.
IPv4 remains widely used but has a limited address space.
IPv6
- It uses eight groups of hexadecimal numbers.
- It supports many more addresses.
- Format example:
2001:0db8:85a3:0000:0000:8a2e:0370:7334.
IPv6 addresses are longer and appear different from IPv4. They are used where more unique addresses are needed.
Tools Used for IP Lookup
There are many online tools for IP lookup:
- Online geolocation sites let you search a valid IP and see country and city.
- Whois databases provide registry and ownership information.
- Command line tools like
pingortraceroutecheck if an IP responds to a request.
What Data You Can Get
Most tools show non‑personal data. They do not reveal:
- Your real physical address.
- Your name or personal contact information.
They only provide network and location details at a general level.
IP Lookup Uses
Here are some common scenarios where IP lookup is useful:
Network Troubleshooting
If a device cannot connect to a server, administrators use lookup and ping to find network issues.
Cybersecurity
Lookup helps detect suspicious IP addresses that might be attacking a server or scanning a network.
Marketing and Analytics
Websites use geolocation to customize user content based on visitor location.
Legal and Investigative Work
Law enforcement can use IP records to trace illegal activity at a broad network level.
Note that all this is possible only with valid IP addresses.

Reverse DNS Lookup
A related term is reverse DNS lookup. This process finds the domain name associated with an IP address by querying DNS records. A valid IP must have a record for this to work.
Reverse DNS is commonly used in email systems to verify the sender’s domain and reduce spam.
Accuracy and Limitations
IP lookup is approximate. Even with a valid IP, the reported city or latitude and longitude might not reflect the exact physical location of a user. This happens because:
- ISPs assign IPs to broad regions.
- Databases may not be updated instantly.
- VPNs and proxies can mask real location.
Despite these limitations, lookup gives useful general information about network and regional assignment.
How to Correct a Mistyped IP
If you find an IP like 111.150.90.2004, consider:
- Checking for extra digits in an octet.
- Reducing numbers to the 0‑255 range.
- Retrying the lookup tool with corrected format.
For example, 111.150.90.204 is valid and can be checked.

IPv4 Address Classes
IPv4 addresses belong to classes that determine network size and purpose:
- Class A addresses are for large networks.
- Class B are medium networks.
- Class C are smaller networks.
This classification aids in routing and organization of the internet address space.
Public vs Private IP Addresses
Valid IPv4 addresses can be public or private:
- Public IPs are reachable from the internet.
- Private IPs are used within private networks.
Public IPs are the ones used for lookup tools to show location details.
Why This Matters for SEO and Security
For a webmaster or SEO analyst, understanding IP addresses is critical. Accurate IP lookup informs:
- Regional traffic analysis.
- Bot and crawler identification.
- Security filtering and blocking.
Invalid strings like 111.150.90.2004 do not provide this information, so always ensure the format is correct before running a lookup.
If you need details about a specific, valid IP address, entering it into a professional lookup tool will show network and geolocation data based on established IP registries.
