There are a lot of terms in the domain world that twist the head even more experienced users. In this help, we’d like to explain some of these concepts.

DNS terms:

• A record  – Used to enter the IPv4 address into DNS domain records to which server it is intended to target eg 80.0.0.250

• SPF record – Is an email validation system used to defend against SPAM. Verifies the sender’s IP address
