+Since getting myself a raspbery pi 5 and getting a proper internet infrastructure 
+at home i wanted to get into some form of selfhosting.
+but not having static ip prevented me from having an easy way to access raspbery pi
+from internet.
+
+i did try to not care at first but ip address changes every several 
+days and that forces me to update it regularly.
+
+as a solution i looked at the dynamic dns services and no-ip had 
+free tier option but in free tier you have to use a domain name under their domain
+like `example.ddns.net`
+
+I didn't wanted to use their domain name so i didn't manualy updated my ip address when 
+things broke for a while
+
+after some thinking i remembered i needed to set `CNAME` 
+records for setting up github pages on my domain name so i looked at what exactly is 
+`CNAME` records are and read the [awesome blogpost][1] by Cloudflare explaining what they are.
+
+so `CNAME` records allows you to point that domain to ip address of another domain name so my 
+`CNAME` record pointing at `alper-celik.github.io` will resove ip of `alper-celik.github.io`
+and use that ip address to acces my domain.
+
+also good thing is since webservers get the domain you'r coming from they can serve different 
+content to different domains from same ip address.
+
+so i created free tier no-ip account and set it up according to the [getting started guide][2] and then
+i added `CNAME` record pointing my domain to their dynamic domain so by doing that i have dynamic dns under
+my domain name using no-ip's free tier
