Description

When configuring the IP address of the zk server on the client side to connect to zk, the connection establishment time is high。Mainly because Obtaining the hostname of the address takes approximately 5 seconds. 3.4.6 has mechanism to safely avoid reverse DNS lookup，but 3.7 don't do that。

1.What's the reasone？

2.Can we modify the method StaticHostProvider/resolve() to avoid reverse DNS lookup?
