A subnet mask is used to identify the network number of an IP address. When a mask is used
to determine a subnet in a network, the mask is regarded as a subnet mask.
Signamax switches only support network masks which are composed of several continuous “1”
bits with left alignment.
In addition, Signamax switches support assigning many IP addresses to a
broadcasting/multicasting network interface. So you can assign some unlimited assistant
addresses, which can be used in various occasions.

1. There may not be enough host addresses for a specified network segment. For
instance, your subnet allows up to 254 host addresses for a logical subnet.
However, your physical subnet has 300 actual host addresses. Two logical subnets
on the physical subnet can exist after introducing secondary IP addresses to a
router or an access server.
2. In the past, many networks used Layer-2 bridges, instead of subnets. The use of
the assistant addresses can help covert the network into a subnet, which is a
network based on switches. A bridge switch in an old network can easily establish
several subnets in this network segment.
3. Two subnets in a single network can be separated by another network under other
conditions. You can establish a network from subnets, so that these subnets can
be separated physically by another network by use of assistant addresses. A
subnet cannot appear at several active interfaces at the same time.
If any switch in the network segment uses an assistant address, all the other switches in
the same segment should use the assistant addresses in the same network or subnet.
