Now that we’ve established what a domain name is, let’s recap what comes after the “www.”:
Top-level domains are the part after the second dot—for example, “.com,” “.net,” or “.eu.”
Second-level domains are the words between the two dots, for example, “Yahoo,” “Facebook,” or “Google.”
TLDs can be general like “.com” or country-code like “.co.uk”, “.au,” or “.us.”
