JS> If a non-standard port is in use I use the syntax INA:FQDN/IP:<port>
Different protocols use different ports. A port is associated with one specific protocol and one protocol only. If a protocol uses a port not standard for that protocol that non standard port applies to that protocol only. Therefore a non standard port should be attached to the protocol flag.
The INA flag is not a protocol flag, but a server address flag. It never carries a port number, just an address.
The system is connectable via steppingstonebbs.com and supports two protocols: IBN and ITN. ITN via the standard port 23 and IBN via the non stamdard port 24555.
From FTS-5001.006:

There are five classes of Internet Capability flags:
.1 Internet Protocol Flags --------------------------
Internet Protocol flags use the syntax:
<flag>[:<server address>][:<port>]
Where <server address> is: * a fully qualified domain name (FQDN), or * an IPv6 address encased in square brackets, or * an IPv4 address in dotted-quad format
and <port> is the decimal service port number. A port number should only be specified if it is not the default port number for that protocol.
Default Flag port Description --------------------------
IBN 24554 Binkp (FTS-1026 - FTS-1030) IFC 60179 RAW ifcico (FTS-1024) IFT 21 FTP (RFC-0959); Note there is currently no widely accepted authentication scheme for FTP transfers by Fidonet mailers. ITN 23 Telnet connection using FTS-1 or any other protocol designed for classic POTS and modem. IVM 3141 Vmodem connection using FTS-1 or any other protocol designed for classic POTS and modem. IP none Mostly used during the introduction of IP capable systems to the nodelist. Denotes an unspecified protocol. (Deprecated)
.2 Server Address Flags -------------------------
Server address flags use the syntax:
<flag>:<server address>
Where <server address> is the same as for protocol flags. These flags are used to specify a server address for Internet Protocol Flags that do not specify an address themselves.
Flag Description -------------------------
INA This flag sets a default server address used for any Internet Protocol Flag that does not specify its own.
.3 Internet Information Flags -----------------------------
Internet Informations Flags use the syntax:
<flag>
These flags are used to signal additional information regarding the internet connection.
Flag Description -------------------------
INO4 Indicates that an otherwise IP capable node is unable to accept incoming connections over IPv4. (FRL-1038) ICM Node accepts mail 24 hours a day using all listed TCP/IP methods, but not all of the other listed methods (such as PSTN/ISDN) and therefore cannot be CM. See FRL-1017. See also the CM flag under section 5.1
