I think you can use nicaliases

Subject: [EXTERNAL] [xcat-user] DNS for multiple networks?
I currently have three networks defined in xCAT; When I run makedns xCAT is
creating the zones for each of these, but the dns is only being generated
for the "compute.lan" domain. The zones are created by xCAT
in /etc/named.conf correctly when running makedns.
What I would like is the following names to be resolvable for the host
"b1-1": b1-1.compute.lan b1-1.compute.ib and b1-1.ipmi.lan
Is there a way to do this with xCAT?
Network Defs:
# lsdef -t network compute.lan
