VerifyIP blocked DNS style

**BUG REPORT**
1. Please describe the issue you observed:

- What did you do (The steps to reproduce)?
I deploy rocketmq on k8s, and use coreDNS addr to connect it. then i was blocked by VerifyIP function

- What did you expect to see?
do not intercept connect when the addr not like ipv4 and ipv6
if the addr actually wrong, the tcp connection will failed and it will sign definite error

Start at the VerifyIP entry point and reproduce the connection using the CoreDNS address described in the report. Check how non-IPv4 and non-IPv6 addresses are handled, then verify that invalid endpoints still produce a definite TCP connection error without being intercepted prematurely.
