Admins may need to scan IPv4 or IPv6 networks, integrate with DHCP and DNS servers, and reach into cloud and virtual environments. A wireless network scanner can also incorporate wireless access points and other wireless devices. Network scanning is in part for understanding how IPs are used. It can be used to identify used IP addresses and discover subnets, and discover IP address conflicts. ICMP ping scans can typically help you view the IP addresses on a network, catch subnet capacity issues, and resolve related issues. ![]() This type of IP address network scanning involves sending a single ping to all the IP addresses within a certain range and then using another protocol to extract data from the device responding to the ping. Network scanning is also about understanding the devices on a network, which may require using the SNMP protocol. SNMP can use object identifiers (OIDs) to identify particular devices, see how they’re used, and track their health. This process involves a management information base (MIB) to help define network objects.
