The IP address / mask combination would tell you. Since the address/mask
was 10.20.1.104/30, you know that this is not a valid host because a network
with a /30 mask always begins on a number that is a multiple of 4. The /30
indicates that there are 2 valid hosts, 10.20.1.105 or 10.20.1.106,
10.20.1.104 identifies the network (a multiple of 4), and 10.20.1.107 is the
broadcast address. So the next available network is 10.20.1.108 and if it
has a /30 mask also the valid hosts are 10.20.1.109 and 10.20.1.110, with
10.20.1.111 as the broadcast address. Hope this helps.

That's what I couldn't figure out.
I think 10.20.1.104 must be host ip address, not network address.
Am I understanding wrong?
Like you recommended, I was able to ping 10.20.1.105 and 10.20.1.106.
But how did you know that it was 105 or 106 instead of 102 or 103?

Jeongwoo,
I'll only make one suggestion in saying with the /30
mask what exactly are you pinging when you ping 10.20.1.140... Is
that a
valid host or the network.. :-> I'd recommend trying to ping
105/106....
HTH
Nigel..
