Detailed Website Analysis

The basic overview not enough? Let's dive deeper.

u2math.co.kr Safety Information

Website safety is a key factor that should not be underestimated. After all, our computers and personal information stored on them are not as secure as one might think - the recent flaws found in microprocessors only confirm this. There is more than one source for finding out if a website is safe to visit or not, some more dependable than others. In this section we'll try to cover all the bases, if at all possible.

• Craeted by Symantec - a California based cyber security experts - Norton is among the most recognized security solutions you'll come across. Because of that, we put a lot of faith in their findings. Symantec assessed u2math.co.kr with its Norton software and found it to be no_data. The experts did not identify any annoyance factors on the website. Symantec could not find any computer threats. And to finish this report on a bright note, no identity threats were found!

Page speed overview

• It takes around 5.7356 seconds for the homepage to fully load. If it were up to us, we'd urge the webmaster to improve. The result isn't very good, you see. Just saying.
• It's worth to note the HTML of the page is around 25.5 kilobytes in size. A good result that should not impact load speed in any negative way.
• Judging by tags, the homepage contains at least 92 images. This is an ok number of images to have. Not too many, but not too few, either.
• Our database tells us around 105 server requests are made before the homepage is loaded completely. Wow, that's a lot. Certainly, so many server requests contribute to slower page load times.

Alexa rank up close and personal

Alexa, perhaps the oldest ranking system of its sort, bases it's website rating on approximated number of visitors of a specific page. In other words, the more visitors, the higher the global and local ranks. As of recently, Alexa has well over four million websites ranked. Having said all that, Alexa rank should be taken with a grain of salt. Or a massive bucketload. In other words, we think it to be greatly overrated, as it never takes into account how popular a website is within its niche.

• Alexa claims u2math.co.kr takes up 890,720 place globally, among all the indexed websites. We updated this information on 2018-01-22.

Host Server In-Depth

What is a server? It's basically a physical storage device (one that, sometimes, makes up several virtual servers for the cheaper shared hosting) that holds all the files and databases associated with a specific website or websites. Obviously, it's a touch more complicated than that (servers also have processors), but the essence is quite simple - your browser contacts the server, which then sends all the neccessary information and files to your computer. Each physical server has a unique IP address assigned to it, too, for easy recognition.

• The current IP address for this website's server is 222.231.25.119.
