Systems behave differently when they have IP conflicts. If you poach addresses, and then they conflict with someone else's system, the results can be painful, like job ending. I don't think that the other posters have thought seriously about what can happen, and part of the danger is that the results of IP address conflicts are unpredictable: If you project is worth of a little extra effort, some organizational love will go a long way. ![]() This is really in everyone's best interests. Or ask the DHCP administrator to allocate a range of IP address for your personal use, but not serve them out of DHCP. If they say "no", do some leg work, and ask your manager to ask their manager to do it. DHCP makes network administrators often think it is purely technical, but the protocol is well designed and can easily support your needs with a little bit of political negotiation.ĭHCP has a feature where certain systems can be given the same IP address every time (in other words, the assignment mechanism can be dynamic, but the assignments themselves can be fixed).Īsk your DHCP administrator to create some entries for you. Network address management is implicitly an organizational (not a technical) activity. You should not be doing this unless you know what you are doing, and asking how to do it suggests that you do not. If you have a favorite that isn't listed here, feel free to leave a comment.You really should not be trying to find unused IP addresses on a network that uses DHCP. Simply enter the range of IP addresses you want to scan and click Start:Īs you can see, there are several high quality and fast IP scanners for Linux. Angry IP Scanner is one of the few IP scanners for Linux that has a nice GUI. There are 32 and 64 bit Deb and RPM files for Debian/Ubuntu and Fedora/RedHat/Suse/Mandriva.

MAC Address: 00:0E:2E:3A:C1:2D (Edimax Technology Co.) Sudo nmap -sP 192.168.1.1-254 #Scans the obvious range To scan for alive hosts on a network, run any of the following commands (they all do the same thing): I rated nmap #2 because it returned the results slighty slower than arp-scan, and there is no -l switch to automatically determine the network settings, as with arp-scan. nmap – Nmap, better known for its port scanning abilities, is also quite suitable as an IP scanner. Sudo arp-scan -l #Scans the local network The easiest way to scan the network you are in is to run any of the following commands (they all do the same thing): By simply adding the -l switch to arp-scan, it will automatically determine the network settings and scan the network of the first adapter. I rated arp-scan #1 because of its simplicity and speed. It sends ARP packets to specified hosts and displays any responses. arp-scan - Arp-scan is an easy-to-use tool that can find alive hosts on a network. Here is a list of the 3 best IP scanners for Linux, rated on speed and usability.ġ. ![]() In Linux, however, you may be searching a little harder to find a quality, easy to use IP scanner. If you are searching for IP scanners for Windows, you will surely find an abundant supply of them.
