correctIPs

My solution:

CREATE PROCEDURE correctIPs() 
BEGIN 
  SELECT id, 
         ip 
  FROM   ips 
  WHERE  ip REGEXP 
"^((25[0-6]|2[0-4][0-9]|1[0-9][0-9]|[1-9][0-9]|[0-9])\.){2}[1-9][0-9]\.(25[0-6]|2[0-4][0-9]|1[0-9][0-9]|[1-9][0-9]|[0-9])$" 
 OR ip REGEXP 
"^((25[0-6]|2[0-4][0-9]|1[0-9][0-9]|[1-9][0-9]|[0-9])\.){2}(25[0-6]|2[0-4][0-9]|1[0-9][0-9]|[1-9][0-9]|[0-9])\.[1-9][0-9]$" 
ORDER  BY id;
END
