I tested it in kubernetes as following steps:

  1. start a deployment named nginx without service.
  2. run ./tcp-proxy -r nginx:80 in another pod, curl http://127.0.0.1:9999 works fine.
  3. then stop nginx pod and it will restart another one, and curl http://127.0.0.1:9999 , it timeout because nginx:80 's ip is changed.

Yep, this is an issue, name resolution happens once on start
