The differences between hash:ip and hash:net.

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



Hi all,

>From the ipset manpage, I can see the following depictions:

hash:ip
  The  hash:ip  set type uses a hash to store
  IP host addresses (default) or network addresses.

hash:net
  The hash:net set type uses a hash to store different
  sized  IP  network addresses.

So, it seems that both types can be used to store the network addresses.

Hence, my issues are:

1- Since the hash:ip can be used to store both host addresses and network 
addresses, why the developer design another set type hash:net?

2- It's well know that any host addresses can be written into the form of 
the 32-bits cidr prefix form. Since the ipset type hash:net should also 
can be used to store the host addresses and network addresses.

In one word: what's the differences between hash:ip and hash:net?
