Hi everybody,

We make use of variable subnet masking on some of our IP-Address ranges.
An example:    In subnet 10.1.0.0 we use the first 64 adresses as host adresses,
in other words with a mask of 255.255.255.255.
          The rest of the adresses are assigned to point-point links, with a
mask of 255.255.255.254.

What happens now is that Netview discovers host 10.1.0.4 as a network. If you
apply the 255.255.255.254 mask to this address, it is indeed a network, but in
reality it is a host. Even worse: Netview thinks that host 10.1.0.3 is a
broadcast address.

How can I convince Netview to apply a 32 bit mask to the first 65 hosts, and
another mask to the rest of the adresses in this range?

Any help appreciated.
