I use similar "clever tricks", albeit with SSH and socks to do the same type of testing. DNS can be funky, its useful to test resolution externally and internally. Traffic can be funky when routed, its useful to t-shoot sites through a proxy here and there as there have been times it works internally and is broken externally (often security appliances are inline that may need debugging). Working in IT infra/ops means its our jobs to use some of these tools to troubleshoot these methods.
