what if i say conversion of name space to IP domain is done by DNS,? 😀.
TCP. Ip and Http are transport, network and applciation protocols, name space has nothing to do with them

Hi , i tried to go in depth to understand this ,do not know whether its completely right but hhtp used URL for name space , IPV4 used class of Internet addresses A,B,C,D reserved for internet multicast communication ,TCP is implemented over Ip uses sequencing mechanism for name space , please verify this answer !!

I think you are getting little confused here. Let me try explaining using OSI model for reference.
When you type : http : // crazyengineers <.> com in the URL toolbar , you are asking CE server to give you the http format of home page. That is where your http comes into picture
later, since your computer( or for that matter any router/computer) wont understand what 'crazyengineers' means.
hence with the help of its own Ip address and default gateway details ( ISP details) provided by the ISP ( sometime DNS details as well), your computer recieves the DNS response sayinh -" crazyengineers.com" corresponds to IP x.x.x.x
IPV4 is currently being replaced with IPV6 . and this is the name space to address space conversion.
you can as well check the DNS details ( i forgot the command) from your windows computer.

once yu get the ip address, your computer thiks -" umm this is not in my network" and sends it to the default gateway which is your router.

after that the presnetation layer encapsulates and the session layer sends a session intiation request to the destination server saying -" hey lookl, i need some of your time"
then comes your transport layer , either TCP or UDP is used, where the transport layer makes surethat your information is trnasported between your computer and the server properly without errors.

All form part and parcel of data communications, and everything has its own purpose.
