Question:

Why can't I resolve other A records in my domain?

For example: you have DNS record with Domain "zyxel.com"

And you can't resolve "www.zyxel.com" or "nebula.zyxel.com" afterwards

Solution:

This is normal behavior, when you have zyxel.com domain, it will act as NS for zyxel.com.

So every requests of "*.zyxel.com*" will matched.
