DNS Qustion Missed onTest

By ajstancato ·
I believe I missed this question on my Admin Solaris II test. Who knows the answer?

If you are only configuring an INTRANET, do you use DNS?

No,you donot have to link domain names to IP addresses.It does not have to be routed over internet to locate addresses.

Thats an interesting question. The first reply is right for now, but the reason the question is interesting is that you don't have to use DNS, but you could. Why would a user want to type an IP address in a URL to get to an intranet page when theycan type in a name that makes sense? That is when DNS becomes useful even for the intranet. And in that case even for the internet. Theoretically if you new the IP address for every internet site you want to go to you could type it in and not need DNS.

It gets even trickier with the fact that some services do need reverse lookup for security to work so DNS will be needed if you use any of those services on your intranet.

Very interesting...

My answer would be yes, because you never know if you are going to change the IP address scheme of your network - and all of those users have hardcoded bookmarks!

Bad question!

In my experience, you are better off using dns for all hosts, even if you wun NIS/NIS+. I only make host entries for bootp clients. I set NIS to look at DNS too. DNS is a much more universal medium of exchange for names and addresses than NIS/NIS+.

If you had a "solaris only" site and all the machines belonged to one domain you could implement an effective naming solution without DNS. Otherwise, DNS is the way to go.
