What are top-level and second-level domain names?
Dot Com (.com) was the first domain type to be introduced and is considered a top level domain or TLD. Top level domains include any that contain only one suffix — for example .net, .info, .biz and so on.
Second level domains or 2LDs are domain names containing another level after the .com or .co suffix. For example, .com.au is a second level domain style as it contains an additional suffix after the .com that shows the website originates in Australia.
What are gTLDs and ccTLDs?
A gTLD is a generic top-level domain and includes addresses like .marketing, .estate, .fashion, and .photography. This is an area really booming in popularity lately and there is a huge range to choose from, whatever your industry!
ccTLDs are country code top-level domains which are usually restricted to certain countries. These are domains like .au, .uk and .us
