Yes, if you're using 9.3 or newer, but note what the manual says:
   If a host name is specified (anything that is not an IP address range   or a special key word is treated as a host
name),that name is   compared with the result of a reverse name resolution of the client's   IP address (e.g., reverse
DNSlookup, if DNS is used). Host name   comparisons are case insensitive. If there is a match, then a forward   name
resolution(e.g., forward DNS lookup) is performed on the host   name to check whether any of the addresses it resolves
toare equal to   the client's IP address. If both directions match, then the entry is   considered to match. (The host
namethat is used in pg_hba.conf should   be the one that address-to-name resolution of the client's IP address
returns,otherwise the line won't be matched. Some host name databases   allow associating an IP address with multiple
hostnames, but the   operating system will only return one host name when asked to resolve   an IP address.)
 

My bet is you don't have reverse DNS set up correctly for that address.
