There seems to be a lot of incorrect/outdated information online about this. The suggestion from Eugene is also useful. I should be able to use setsockopt() with IP_PORTRANGE_HIGH if I cared to use the high range only. I probably don't want to do that in most cases, but it's good to understand what the differences are.
