-3, --bootp-dynamic[=<network-id>[,<network-id>]]
(IPv4 only) Enable dynamic allocation of IP addresses to BOOTP clients. Use this
with care, since each address allocated to a BOOTP client is leased
forever, and therefore becomes permanently unavailable for re-use by
other hosts. if this is given without tags, then it unconditionally
enables dynamic allocation. With tags, only when the tags are all
set. It may be repeated with different tag sets.
