Type any web address and look at the last piece after the final dot, .com, .org, .io, and that’s the domain extension<\/strong>. Small string. Big implications: it marks where a name sits in the internet’s naming hierarchy, and it quietly decides who governs it, what it costs over time, and how much risk rides along.<\/p>\n\n\n\n

Most explanations stop at “it’s the part after the dot,” which is accurate but thin. The sharper question is why one extension runs two dollars while its neighbor renews at sixty, and why certain suffixes turn up in phishing reports so much more than others. Cost and risk, not spelling, are what actually separate one extension from the next, and that’s the ground this guide covers.<\/p>\n\n\n\n\n\n\n
