In summary, InetAddress.getLocalHost() will typically work, but you may need to provide an alternative method for the cases where your code is run in an environment with “complicated” networking. Detect OS (Original Version) This code can detect Windows, Mac, Unix, and Solaris. Another variation is to to get the IP address from a config file or a command line parameter. This article shows a handy Java class that uses System.getProperty('os.name') to detect which type of operating system (OS) you are using now.A variation of the previous is to get the preferred FQDN from a config file or a command line parameter.(But how do you get it, and how do you deal with a DNS-based load balancer?) Another approach is to (somehow) get the externally advertised FQDN for the host, and use InetAddress.getByName() to look up the primary IP address.One approach is to use Java’s NetworkInterface.getNetworkInterfaces() API to get all of the known network interfaces on the host, and then iterate over each NI’s addresses.What this means is that the IP address returned by InetAddress.getLocalHost() might not be the right one to use. Some could be virtual devices, and others could be private network IP addresses. And to top that, not all IP addresses will be reachable from off the machine.

On the other hand, we can perform very flexible operations on an array of characters, we will be using this property of character array to sort our string. The problem is that a host could have lots of network interfaces, and an interface could be bound to more than one IP address. Another difficulty is Strings are immutable in Java, which means we cannot modify the original String.

On the face of it, InetAddress.getLocalHost() should give you the IP address of this host.

Once installed, execute the following command in your terminal (Mac OS) and. Java MAC toMACAddress(String macAddress) Previous Next. So the method which helps to get the IP address for any Host is getHostAddress() of InetAddress class. There are many ways to get the IP Address of a particular host. Every site has its own host link to their own IP Address which helps to send the request by the user to the HTTP traffic and helps to collect the information which the users want This is how an IP address is necessary for every host. When connected to the internet, the IP address allows the computers to send and receive information. IP addresses are usually written and displayed in human-readable notation such as 192.168.1.35 in IPv4(32-bit IP address). It is an identifying number that is associated with a specific computer or computer network. IP Address stands for internet protocol address.
