Use host and nslookup: Linux System Engineer: Web Servers and DNS Using Apache, NGINX, and BIND

The host command is pretty simple, it resolves a hostname to an IP address and that is all. Nslookup is an older tool that has its own resolution engine. It was deprecated but has now been restored to full preferred status with dig. When troubleshooting DNS issues it can be nice to have two different tools which resolve DNS names using different code. Nslookup satisfies this need.
