Works fine for me. The only case I get the IP address instead of the 
host name is when there is no A entry in the DNS server's zone file. 
When you use nslookup/host/dig to make the same requests do you get a 
name? Do you have a correct /etc/resolv.conf? What versions of FreeBSD & 
JDK do you use?
