title: Amazon Web Services - Length of HostIds returned
body: <p>I'm making a platform that requires allocating hosts programatically. The API returns a HostId, that's a string. (Source: <a href="http://boto3.readthedocs.io/en/latest/reference/services/ec2.html#EC2.Client.allocate_hosts" rel="nofollow noreferrer">boto3 docs</a>). If anyone has experience dealing with AWS, could you tell me if this string has a constant length? And if it does, how long is it?<br><br>
  This is from the perspective of designing a database - specifically for setting a maximum length to the field. I don't want to assign the host ids superfluous space. <br></p>
