Are AWS Security Group Port Ranges Inclusive or Exclusive

Question

AWS security groups allow a port range to be specified for permitted traffic, written in the form 1234-5678: would that be inclusive of ports 1234 and 5678, or exclusive of either/both of those ports?

The documentation doesn't seem to describe this.

Answer 1

Since example shows 0 - 65535 and 2^16 is 65536 (otherwise it would be -1 - 65536), than it means inclusively.
