I kind of know why glue records are needed (cyclic dependencies), but when are they needed? Are they only needed when setting a domain's nameservers to my own machine on the internet - like "ns1.mydomainonmyserver.com" ??

Is there any need / point in making glue records when using external / hosting provider's nameservers?

Beginner question sorry (T_T)
