for ip address
what does /24 mean in
123.123.123.123/24?
@Acer The /24 is just a subnet mask, which is just used to divide the address into a network address and a host address. In this case, the network address makes up the first 24 bits (3 bytes), so 123.123.123.0.

So if I apply a filter in wireshark like ip.addr == 123.123.123.123/24,
it will match ip from 123.123.123.0 to 123.123.123.255.
Is it correct?
@Acer It should, although people generally specify subnets using the network address: ip.addr == 123.123.123.0/24.
It's also worth noting that 123.123.123.0 is the network address and 123.123.123.255 is the broadcast address, so hosts won't be able to bind to those addresses.
