Yes and no. In this case, the mask is used to determine the number of
bits in the address that are relevant to the rule, so:

192.168.1.1 255.255.255.255 - All bits are relevant, so the entry
applies only to that exact address.
192.168.1.1 255.255.255.0 - The first 24 bits are relevant, so the entry
applies to 192.168.1.x
192.168.1.1 255.255.0.0 - The first 16 bits are relevant, so the entry
applies to 192.168.x.x

I think in this case, the problem is that 'local' is specified, which
generally applies to Unix domain sockets, and that one column is missing
as Keith suggested:

> local all 10.17.11.0 255.255.255.0 trust

To let hosts with an address of 10.17.11.x in, the entry should probably
be:

host all all 10.17.11.0 255.255.255.0
trust
