Today i started getting a problem,,, every ip i choose to configure it returns IP CONFLICT WITH ANOTHER SYSTEM....think might be virus or hacker since all ips are not assigned.

please help my network is down.

Do you have proxy-arp on your interface facing your network? Does that interface have ip address ranges assigned to it?

If you post your configs we can help more...

Same problem I faced from my ISP end

Do You have any bridged interfaces ?

no bridges interface,,, i did fing a customers cpe which had 10 times pps as the others so i did block him and the problem has gone... now am not sure if virus, spam,, or cpe is the problem.
