Interrogating Domain Names

Introduction

Console commands can be quite useful not least for which the immense power they provide given the size of the application, "nslookup" is one such command although by enlarge replaced by the "dig" command, both apparently perform the same or similar function. Both these commands perform the function of lookup for a given domain name returning a four or six digit sequence of decimal numbers separated by periods "." this number when returned gives numbered address assigned to that domain. This you might already know, what you might not know is that any given domain name can hold more than just one numbered address. What is the point of that I here you ask?
