It's valid and it's called a noncontiguous subnet mask since the 16 bits for the subnet mask are not contiguous. The RFC's, however, recommend against using noncontiguous subnet masks.
I really wish to know
-The subnet mask identifies what bits in the IP address are to be used to represent the network/subnet portion of an IP address. [A0D]WWK
That is your subnet mask.
It does not require a subnet mask.
If this is a default subnet mask, then it would be a class C subnet mask. If you are subnetting a network and this is not the default subnet mask, then it could be either a class A or class B.
The default subnet mask would be 255.255.0.0
The default subnet mask has a standard size. The custom subnet mask allows you to make subnets that are smaller or larger than the default.
Default Subnet mask: 255.255.0.0
The default subnet mask is 255.255.0.0
default subnet mask for 198.25.4.129
It is called a subnet mask. A subnet mask is used for dividing IP addresses into host and network addresses.
2 given subnets
A default subnet mask gives you classful addressing on octet boundaries. A non-default subnet mask implies that you are subnetting a larger network into several smaller ones.
subnet mask defines how many network bits our network address is using. In default condition subnet mask of the given ip address is 255.0.0.0 subnet mask may change if we do subnetting.
Subnet mask for the above is 255.0.0.0
