Flavio Junqueira commented on ZOOKEEPER-1666:
---------------------------------------------

Never mind, I've seen it in the v1 patch for 3.4, but the v2 patch has the curly braces aligned
just fine, +1.

> Avoid Reverse DNS lookup if the hostname in connection string is literal IP address.

> In our ENV, if the InetSocketAddress.getHostName() is called and the host name in the
connection string are literal IP address, then the call will trigger a reverse DNS lookup
which is very slow.
> And in this situation, the host name can simply set as the IP without causing any problem.
