I found another way and it's simpler, but does have a drawback:

ubuntu at maas:~$ rmcp_ping
10-0-0-102.master IPMI
10-0-0-101.master IPMI

It's printing hostnames instead of IPs, which is rather annoying.

rcmp_ping is from the openipmi package and does broadcast pings by
default.  It's a shame ipmiping doesn't do that, and seemingly can't be
made to do it either:

ubuntu at maas:~$ sudo ipmiping 255.255.255.255
ipmiping 255.255.255.255 (255.255.255.255)
ipmiping: ipmi_sendto: Permission denied
