The user adds some addresses and I want to find out if they're valid before running a complex series of networking scripts. Like give him feedback if that address is already taken. Is there an ip addr command which will test if an addr is already taken on the network without doing an add? Conversely, he wants to assign a gateway, can ip find out if that address exists without adding a route? TIA _______________________________________________________________ Have big pipes?
