Do we need to purchase domain

- to configure DNS server

- to configure Mail(sendmail) server

- to configure web(apache) server

Well what are you talking about???

are you talking about an in-house web/mail/DNS server???

If you want to set up a domain at your home/office.. than no you don't need to purchase a domain name.. goofball...

the only reason to purchase a domain name is if you are going to host your own internet based website... i.e. www.yourname.com

To do this you need to have a static IP address... These can be obtained from you internet provider for a fee..

When you purchase the domain name, you will tell then what the IP address is... (you static, external IP address)

Then, if you have a router.. you need to configure port forwarding on your router to forward all access of port 80 to the internal ip address of the webserver.. i.e. 192.168.0.1 or something of that nature..

Tada! You gotchoself a website... lol.. like my word?

New bie:

suppose i need to configure

a mailserver

and i need a mail id as aa@aa.com then it can be possible without purchasing domain name.




And is there any sequence should be followed learn server

1)DNS
2)Mail
3)Apache

or any things is related in DNS and Mail server. or we can learn any server first as our wish....

Yes... if you want to have email like aa@aa.com then you would need to purchase "aa.com" and just as you would with the external web server... you would tell the domain name reseller your static IP address...

I still don't understand what you need DNS on your server for though...

The only reason *YOU* would need DNS services is if you have several computers on your network and you are setting up an internal domain... so you could have different users and mail addresses... is this what you're doing???

i.e. - you want aa@aa.com, bb@aa.com, cc@aa.com for email???

Thankx for ur response,

And,
Yes u are right !

-whether it is necessary to host aa.com to configure that mail id... or by only purchasing that mail id it will work
