Is is NOT in the spec here as taken from the nodelist:

;S | IBN[:24554] ......... BinkP protocol                                     

and for INA:

;S | INA[:IP-addres] ..... Flag sets the default Internet address used for    
;S |                       any non-email based IP-flag that does not specify  
;S |                       its own.

Just as well we ignore that data other than as a name ' ish.

In the 20 odd years I have been in fido I have never seen this mode not that I
have been looking mind you and as far as I can see if there is a defined
location for a ip address/url eg, INA that is good enough for me.

It would be interesting to see what Ward's options are on this?

Well I assume you mean all three variations e.g., URL, IP4 & IP6 when it is
needed and no I have not tested it for IP6 and coming to think about it have
not noticed IP4 as well.

Mbse is not the only one that looks for the URL/Ip address from the INA flag.
It is what the INA flags is for.
