It ret urns a port within the ephemeral port range 49152-65535 (RFC 6335 and IANA). https://blog.inlab.net/posts/f2568/ Sun, 01 Jun 2025 00:00:00 +0000 https://blog.inlab.net/posts/f2568/ <code>f2568()</code> is a variable length tabulation hashing function which returns a 64 bit hash result of input data up to a size of 256 bytes. It&rsquo;s fast (requiring as many XOR operations as the data length in bytes), easy to understand and very strong at the same time. <code>f2568()</code> is publicly available under the BSD-3-Clause License.
