Reference
[RFC6335]
Note
Service names and port numbers are used to distinguish between different
services that run over transport protocols such as TCP, UDP, DCCP, and
SCTP.

Service names are assigned on a first-come, first-served process, as
documented in [RFC6335].

Port numbers are assigned in various ways, based on three ranges: System
Ports (0-1023), User Ports (1024-49151), and the Dynamic and/or Private
Ports (49152-65535); the difference uses of these ranges is described in
[RFC6335]. According to Section 8.1.2 of [RFC6335], System Ports are 
assigned by the "IETF Review" or "IESG Approval" procedures described in 
[RFC8126]. User Ports are assigned by IANA using the "IETF Review" process, 
the "IESG Approval" process, or the "Expert Review" process, as per 
[RFC6335]. Dynamic Ports are not assigned.

The registration procedures for service names and port numbers are
described in [RFC6335].

Assigned ports both System and User ports SHOULD NOT be used without
or prior to IANA registration.

https tcp HTTP over SSL/TLS [Tim_Berners_Lee] [Tim_Berners_Lee] Web browsers like Safari and Internet Explorer (with the Bonjour for Windows plugin) DO NOT browse for DNS-SD service type "_https._tcp" in addition to browsing for "_http._tcp". This is a conscious decision to reduce proliferation of service types, to help keep DNS-SD efficient on the network. Today, if a user types http://www.mybank.com/ into their web browser, the web server automatically redirects the user to https://www.mybank.com/. Rather than having an entirely different DNS-SD service type for https, we recommend using the same redirection mechanism: advertise a plain "http" service, which consists of nothing except an HTTP redirection to the desired "https" URL. Work is currently being done on adding mechanisms to HTTP and TLS to allow the server to tell the client that it needs to activate TLS on the current connection before proceeding. If this becomes widely adopted, it further justifies the decision to not create a separate DNS-SD service type "_https._tcp", because security becomes just another one of the things that is negotiated on a per-connection basis (like content-type negotiation today) rather than being an entirely separate thing.
