Hi All,<div><br></div><div>I am facing two issues when using ISC DHCP (Using version 4.2.2). </div><div><br></div><div>When I keep a network address like 7.7.7.0 in range it gets assigned on client.</div><div>Is this correct behavior?</div>
<div><br></div><div>Also when i try to ping on the address assigned by dhclient on an interface i get error "connect: Invalid Argument" , even when i have host addresses in range.</div><div>Can any body please provide me with pointers as to why ping doesn't work?</div>
