I think what you wanted to say was:

# point all domain requests to eunuch
dom=
	ns=eunuch.next.com
dom=eunuch.next.com ip=129.18.11.10

# define plan9 machine
sys=vectra
	dom=vectra.next.com
	ip=129.18.11.148  ether=00a02429ed1d
    bootfile=/386/9pcdisk
	proto=il

# define a class B net to have a submask
ipnet=xyzzy ip=129.18.0.0 ipmask=255.255.255.0

# define a subnet
ipnet=loca ip=129.18.10.0
	ipgw=129.18.11.1

Forget about the soa entry.  It just defines a subtree that
is being served by this machine.  In your case nothing is.
