Say N unless you desparately need the short form of the ip
object commands.

help
If you are not going to use links of type "frad", "econet",
"bif" etc, you probably don't need to enable this.
Ethernet, wireless, infrared, ppp/slip, ip tunnelling
link types are supported without this option selected.
