Fail to ping to Solaris 10 system.

I install Solaris 10 but sometime I could not ping to system but sometime it is ok to ping. Is there any problem with network configuration in Solaris 10 or it is a network environment because I rent my server in the share rack (Data Center) and I dont know other factor that make my server fail to ping for sometime ?

Thanks

I think it is a cause of route. How can I config the correct route?
