The address format of IPv4 is represented into 4-octets (32-bit), which is divided into three different classes, namely class A, class B, and class C. The above diagram shows the address format of IPv4.
29 cze 2015 · The easiest way to check the range is probably to convert the IP addresses to 32-bit integers and then just compare the integers.
One approach is to use NetworkInterface.getNetworkInterfaces() to get all of the known network interfaces on the host, and then iterate over each NI's addresses. Another approach is to (somehow) get the externally advertized FQDN for the host, and use InetAddress.getByName() to look up the primary IP address.

17 kwi 2014 · I want to validate an IPv4 address using Java. It should be written using the dot-decimal notation, so it should have 3 dots ("."), no characters, numbers in between the dots, and numbers should be...
14 lip 2024 · Learn how IP addresses are organized in IP classes and how to identify the class of an IP address. There are two versions of IP addresses, IPv4 and IPv6. In this tutorial, we will discuss how IPv4 organizes IP addresses.
Below is a table providing typical subnets for IPv4. This IP subnet calculator covers both IPv4 and IPv6 protocols, providing information such as IP address, network address, subnet mask, IP range, and more.
