	I have multiple timestamps values  for single ip in a table, I

need the max(timestamp) for each ip I select out.

example:

	timestamp                  ip

	2003-09-29 13:20:23    68.209.182.4
	2003-09-29 13:20:44    68.209.182.4
	2003-10-02 12:53:38    68.209.182.4
	2003-10-02 12:35:06    68.75.94.158
	2003-10-02 12:52:03    68.97.33.69

	Thus

	select distinct ip, max(timestamp) from table

	group by ip, timestamp;

	 

	returns every timestamp value per ip.

	Any ideas on how to get only the max(timestamp) for each ip?
