INTERNAL_SUBNET in draft-ietf-ipsec-isakmp-mode-cfg-05



Why is the INTERNAL_IP4_SUBNET attribute in draft-ietf-ipsec-isakmp-mode-cfg-05
limited to a length of 4 octets?

   INTERNAL_IP4_SUBNET        13     Variable   0 or 4 octets

The example implies 8 octets which makes sense.

   ATTR2(REPLY) =
     INTERNAL_ADDRESS(192.168.219.202)
     INTERNAL_NETMASK(255.255.255.0)
     INTERNAL_SUBNET(291.168.219.0/255.255.255.0)

I don't want to apply the INTERNAL_NETMASK to all the INTERNAL_SUBNETs because
that would assume all subnets to be the same size.

Thanks
