Bonding network adapters

I'm trying to bond 2 NICs and I have some questions about the modifications I have to do in /etc/network/interfaces

Here's what I'm doing based upon articles I found on the web:

auto bond0
iface bond0 inet static
address                     OK
netmask                     Ok
network                     What should I put here?? My network IP range???
broadcast                  What's going here?
gateway                    Ok
hwaddress ether      If I understand correctly, I can put whatever MAC I want as long as it doesn't                         already exists on my network, am I right?
post-up ifenslave bond0 eth0 eth1           Ok

Any explanations would be appreciated since I'd like to understand what I'm doing!

Thanks in advance!
