In a network connection,the network has 60 people connected,when he assigns an ip to 61th person,it doesnt get assigned. Even in a CLASS C server,255 should be the minimum range of ip's assigned,any idea why is that happening?
This seems like the DHCP server is only configured for 60 addresses. You would have to reconfigure it to make more addresses available.
But I get the feeling I am doing your homework for you, right?
Sven is right, however you did not indicate whether the DHCP server was Unix or Windows or "other" - How you have your network Class C laid out eg: 1-10 reserved 11-20 network devices, 21-40 printers 41-100 DHCP 101 - 255 VPN Tunnels and static devices...
With a DHCP server, unless you have a very tiny infrastructure, you would not let DHCP have 1-255. Is this a test? ;^)
