when doing DNSSEC over unreliable upstream network. It comes
with some cost in memory usage and network bandwidth.
Add -use-stale-cache option. When set, if a DNS name exists
in the cache, but its time-to-live has expired, dnsmasq will
return the data anyway. (It attempts to refresh the
data with an upstream query after returning the stale data.)
This can improve speed and reliability. It comes
at the expense of sometimes returning out-of-date data and
less efficient cache utilisation, since old data cannot be
flushed when its TTL expires, so the cache becomes
strictly least-recently-used.
version 2.86
Handle DHCPREBIND requests in the DHCPv6 server code.
