Theseutilities are accessible via the command line and offer the simplest way tofind a list of all device IPs connected to a network. How to Find IP AddressesĪll operating systems offer simple utilitiesto monitor basic networking parameters, including IP address scanning. DHCP plays a crucial role inIP addressing, as there are chances of misconfiguration with manual processes (suchas two or more devices getting the same IP address). In addition to the IP address, DHCP alsoassigns other critical address parameters like the default gateway address,subnet mask, and domain name server (DNS) address. While there are dedicated DHCP servers, in small networks, a routercould also offer DHCP services. A DHCP server assigns an IP address to a host as soon as it enters anetwork. IP addresses are assigned dynamically, usingan automated networking process called Dynamic Host Configuration Protocol(DHCP). IPv6can provide 2 128 unique addresses, which is sufficient to meet allour IP addressing requirements for the foreseeable future. The IPv6 format was introduced as IT practitioners felt the totalnumber of unique addresses served by the IPv4 format (i.e., 4.3 billion) wouldfall short of the demand with the rising number of mobile and IoT devices. Most networks use TCP/IP protocol for networking,which ensures different devices in a network interact with each other. Getting Started-The Basics of IPAddresses What Is an IP Address?Īn IP address is a unique identifier attachedto every node (workstation, server, printer, etc.) on a network to ensure datatransfer and communications. In this article, we’ll discuss to find IPaddresses of all devices in a network, why network-scanning is important, andlist some common tools for the job.
However,most of these advanced tools and techniques for network monitoring still relyheavily on IP address scanning.
IT teams need advancednetwork monitoring tools to keep track of all devices in a network. However, business networks are constantly expanding and contain acomplex mix of legacy and next-gen networking equipment, physical and virtualservers, workstations, personal devices, and more. Network administrators need to monitor their devicesconsistently for faults, overloads, and failures, and routinely upgrade thedevices. This means every device or node in a network needs tofunction properly. Several applications arerequired to run simultaneously to serve critical functions (such as finance,sales, and supply chain). Today, digital networks need to offer 24/7business continuity for employees, partners, and customers to interactseamlessly across different business touchpoints.
