Hi All,

I support this useful draft.

An item I’d like to see added to the “Connectivity Recommendations” list after C_REC#12 is.

   C_REC#??:  Because of the potential for separate parallel IPv4 and 
              IPv6 PDP/PDN connections when the network or subscriber 
              profile does not support IPv4v6 PDP-Contexts, the cellular
	      host must be able to be configured to exclude this type
              from the available options.

For example if the list was just IPv4 or IPv6 (with 464XLAT implied) then the cellular host 
would only ever attempt to set-up a single stack connection. 

I note that with:
	Android the options are IPv4, IPv6 and IPv4/IPv6.
	Windows Phone 8.1 the options are IPv4, IPv6, IPv4v6 and IPv4v6XLAT


Best regards,
Ross
