here's a snippet from the /etc/defaults/varnish file (ubuntu linux)

#DAEMON_OPTS="-a :8080 \
DAEMON_OPTS="-a 2001:4d48:2400:0:NNN:NNNN:NNNN:NNN:8080 \
             -T localhost:8082 \
             -f /etc/varnish/default.vcl \
             -S /etc/varnish/secret \
             -s file,/var/lib/varnish/$INSTANCE/varnish_storage.bin,1G"

where NNN substitutes for the real host IP
