This is a Windows based tutorial so if you run a different operating system please check the Tutorials section for alternative methods. It is really a quick tutorial I’ve just taken lots of images as a few users got stuck; so pay attention and you’ll be fine 
This will aid users who have opened up 000webhost hosting accounts and pointed their domain or used a CNAME record to use this own custom yoursite.com domain; your ISP won’t always have the latest information to load your new hosting straight away so this can help you!
So hit your start menu on Windows 10 and type network and sharing and select the top one.
Now this can change for different users; but if you are on WiFi then it will be WiFi (Network Name) you click on network or if you are on a wired ethernet connection it will be Ethernet (Cable) you click
Now select properties at the bottom of this
Now select IPV4 then hit properties again
Most likely there is no information here at all but if there is then do not change the top one unless you know what you are doing or if your network administrator has said to change it - most computers will automatically grab an IP address from the network but I assign static IP addresses to devices on networks to provide enhanced security & tracking of the users basically by assigning their computer a static IP address and binding it with their MAC address.
Type in 8.8.8.8 and 8.8.4.4
Now save and close all the windows opened.
Now that you are using Google DNS
So when you type facebook.com into your browser your computer goes to Google DNS to find the correct information to load to bring up the site, before when you typed facebook.com it went onto your Internet Service Provider DNS to lookup where to load up; sometimes ISP DNS can be outdated or slow at updating; Google DNS is generally a lot faster at loading websites and having up to date information rather the previous hosting company for example.
Hit start menu again and search for command prompt
Type exactly ipconfig /flushdns noting the space in the middle
Now hit the return key and it should update successfully
Feel free once this has run to hit the up key on your keyboard and it will paste the same command again, you can hit return again then do it once more - three times.
Now exit by closing the window or typing exit then return.
Now load your website in your browser! It should now load your new hosting account fine!
If you are still seeing your old hosting account for example please clear the cookies/data/browsing history on your computer.
Google Chrome: hit settings, search clear data and then run it
Mozilla Firefox: hit settings, privacy, clear data and run it
Internet Explorer:
Options, safety, delete browsing history and run it.
