Subject: Use A(AAA) when querying for domain on cache expire
X-Git-Url: http://git.archive.openwrt.org/?p=project%2Fmdnsd.git;a=commitdiff_plain;h=267686c21f4b31346839ae1d4085d4990fcdc63c

Use A(AAA) when querying for domain on cache expire

When cache entry is (halfly) expired we send query to get an update. So
far we were sending all queries using PTR records but for cached domains
it should be A(AAA) instead.
