It's ugly, but what I do is this

nmap 10.0.1.* | tee ip_map.log
arp -a | tee mac_map.log


If I'm in a hurry, I will just do 

nmap -sP 10.0.1.* | tee ip_map.log
arp -a | tee mac_map.log

But usually, nmap -sP ip-range will give me all the ip-mac addresses.
If something shows up with missing info, then I know someone else is on the 
network, because DHCP assigns by the macs and only to macs it knows.
