We are using nmap as the scanning engine, to do the scanning searching of available host, along with that we will identify the ip address of the host and open port numbers. We are scanning the network to find the available ip address host and corresponding open port on each host operating system. Command: nmap –T4 –A –v 192.168.215.0/24 This command will initiate the arp scanning and scanning the 255 host in the network. Nmap find the host of 192.168.215.150 availability and skip the host down. The above screenshot shows the ip address details of 192.168.215.150, and opening ports of 139,445 and 135. The scan reports three ports opened. 139 NetBIOS port, 445 file sharing port and 135 port net bios ports. DNS SERVER: Domain name server configuration, domain name server is designed to resolve the ip address to name and name to ip address.

DNS Service- It will help in translating the domain names into their corresponding IP addresses. The network will have primary and secondary zones that will be synchronized. The secondary zone will act as a backup in case the primary zone fails. Synchronization will be achieved by the secondary zones requesting updates from the primary zone data. Network performance will be improved by redistributing several DNS query loads across several computers, and also through caching [2].
