name servers getting slammed

For some reason about 3 days ago the bandwidth (viewed in bandmin) on my name servers have gone from 5 meg a day to now over 1.5 gig a day and I have seen my .named process running consistently between 3.0 and 5.0% in top for extended times.

Is there an easy way to see who is hitting my name server so hard or what might be causing this? I am suspecting I may need to find a way to block this unwanted use because at this rate my name servers alone will use 30 to 50 gig a month.
