This topic was covered earlier this week and last week.  Mark Andrews,
Sam Wilson, and Brian Miller  wrote about the RFCs - 952, 1183, and
2181.  There was also mention of the relevant MS Technet articles.
Here is a summary.

952 says that the underscore character is illegal.  952 IS A STANDARD.
1183 (IIRC) says that an initial numeric character is now legal.
     1183 IS A STANDARD.
2181 says that almost any character is legal.  2181 is NOT a standard;
     it is standards-track.

Microsoft decided that it would follow 2181 and use an underscore in
an "A" record.  BIND 8.2.2-p5 by default does not allow the underscore,
but you can change the options parameters to allow it.

I had posted a query twice in the past months about this.  In my case,
the name with the underscore was not in DNS as an entire string; it
was split on two lines 

     $ORIGIN _msdcs.w2k.anl.gov.
     gc      600     IN      A       130.202.224.143

The error message from BIND complained about the name

     gc_msdcs.w2k.anl.gov

and I could not locate that string in the zone.
