given IP address+netmask, is my NETWORK value correct?

[registering]

Hi all,
I"m wondering if someone can just verify these values for me, I'm trying to track down a problem and I'm new to networking.

I have a machine 146.243.232.29 on a network using a netmask of 255.255.255.192. Is the network it's on 146.243.232.0, and its broadcast 146.243.232.62? I believe the network value is just IP_ADDR AND(ed with) NETMASK, and the broadcast is usually the highest value within that network?

Also, I've got another machine 128.223.70.40 using a netmask of 255.255.254.0. Is its network 128.223.70.0 with a broadcast of 128.223.70.255?

Thanks in advance. :)
