+@subsection How MySQL uses DNS
+
+When a new threads connects to @code{mysqld}, @code{mysqld} will span a
+new thread to handle the request.  This thread will first check if the
+hostname is in the hostname cache. If not the thread will call
+@code{gethostbyaddr_r()} and @code{gethostbyname_r()} to resolve the
+hostname.
+
+If the operating system doesn't support the above thread-safe calls, the
+thread will lock a mutex and call @code{gethostbyaddr()} and
+@code{gethostbyname()} instead. Note that in this case no other thread
+can resolve other hostnames that is not in the hostname cache until the
+first thread is ready.
+
+You can disable DNS host lookup by starting @code{mysqld} with
+@code{--skip-name-resolve}.  In this case you can however only use IP
+names in the @strong{MySQL} privilege tables.
+
+If you have a very slow DNS and many hosts, you can get more performance by
+either disabling DNS lookop with @code{--skip-name-resolve} or by
+increasing the @code{HOST_CACHE_SIZE} define (default: 128) and recompile
+@code{mysqld}.
+
+You can disable the hostname cache with @code{--skip-host-cache}. You
+can clear the hostname cache with @code{FLUSH HOSTS} or @code{mysqladmin
+flush-hosts}.
+
+If you don't want to allow connections over @code{TCP/IP}, you can do this
+by starting mysqld with @code{--skip-networking}.
