Which of the following addresses is an accurate IPv4 address?
192.168.0.2
1001.2345.3234.5678
100.234.56.1.3
129.168.10.25678.1
Answer (2)
An IPv4 address consists of four numerical values, each ranging from 0 to 255, separated by dots.
Examine each provided address to check if it conforms to the IPv4 format.
The address 192.168.0.2 has four valid octets.
Therefore, the accurate IPv4 address is 192.168.0.2 .
Explanation
Understanding IPv4 Address Format Let's analyze the requirements for a valid IPv4 address. An IPv4 address consists of four numerical values (octets), each ranging from 0 to 255, separated by dots. We will examine each provided address to see if it meets these criteria.
Checking Each Address
192.168.0.2 : This address has four numerical values (192, 168, 0, and 2), each within the range of 0 to 255. It follows the correct format with three dots separating the values. Therefore, it is a valid IPv4 address.
1001.2345.3234.5678 : This address has four numerical values, but each value is far greater than 255. Therefore, it is not a valid IPv4 address.
100.234.56.1.3 : This address has five numerical values (100, 234, 56, 1, and 3) instead of four. Therefore, it is not a valid IPv4 address.
129.168.10.25678.1 : This address appears to have five numerical values (129, 168, 10, 25678, and 1), and one of the values (25678) is much greater than 255. Therefore, it is not a valid IPv4 address.
Conclusion Based on the analysis, only the first address, 192.168.0.2, meets all the criteria for a valid IPv4 address.
Final Answer The accurate IPv4 address among the given options is 192.168.0.2 .
Examples
Understanding IPv4 addresses is crucial in networking. For example, when setting up a home network, you assign IP addresses to devices like computers, smartphones, and printers. A valid IPv4 address ensures that these devices can communicate with each other and access the internet. If you were to configure a device with an invalid IP address, it would not be able to connect to the network. This knowledge is also fundamental in diagnosing network connectivity issues and configuring network devices in larger organizational networks.
The accurate IPv4 address among the given options is 192.168.0.2, as it follows the required format and contains valid numerical values. The other options either exceed the numerical range or have the wrong number of octets. Thus, only 192.168.0.2 is considered valid.
