DNSProxy - Resolve-Fail - cpsc.gov

Warning: very new to PANOS.

 

I'm seeing a TON of these messages, to the tune of about 2-300 per second in my system log: Failed to resolve domain name: cpsc.gov after trying all attempts to name server(s): mynameserverinternalip.

 

I've read that this domain is a popular one and used in DOS style attacks.  

 

Should I worry or ignore this? Can I prevent it from logging, or is there anything I can do to make it go away?

 

Thanks,
