How do I use nslookup to determine the primary Web server address?

How to change default DNS server nslookup?

On my VPS I have a DNS problem.

Before I was using the default DNS servers of my VPS provider, now I want to change them to the ones of Google's DNS servers. How can I do it? I have been looking around, and there is no way to change it, it seems. I'm using Ubuntu 12.04 Open the /etc/resolv.conf file with the following command: sudo gedit /etc/resolv.conf Remove the lines that say: nameserver 127.1 nameserver 8.8 Replace the lines with the lines that say: nameserver 8.4
Save the file. Reboot the system. This should fix your problem.

How do I use nslookup to determine the primary Web server address?

I want to find the exact URL that is used by a website. That is, an example will go something like: nslookup (what goes here?). And it says, hey look, it's. How do I see what DNS name the web site was originally pointed to? And, if its own domain name, what DNS name does the IP belong to?com ns. Ns.google. 2 in /etc/resolv.conf
Abc. 17 in /etc/resolv.conf
Nsdb.hp. 0 in /etc/resolv.conf
Ns1.conf Any help appreciated. I'm sure I need to set up DNSSEC and the entire concept of reverse DNS and that kind of thing, but I'd really just like to understand this nslookup part. Thanks!
First of all, your last example shows a typo: it's nameserver, not name. What would a nameserver have to do with HTTP protocol, anyway? There are three parts to a NS lookup: nslookup first queries DNS servers to find out which A records match "ns". The default is to query 8.8 or 8.4.

Nslookup then performs reverse-lookups: given the value it finds in step 1, it queries each IP address from the result and looks for an NS in that server. The result could either be IP address of IP address or nothing - it can be a server, an IPv6 host, or a loopback address.

Nslookup tries its best to match the reverse path too, ie it tries to build a path similar to the one used by browsers. So it makes sure the returned addresses are all in the same provider as the target and has the right port number etc.

How to lookup DNS server?

How can I lookup a DNS server for a domain name?

I know I can type ipconfig /all, but how to type "nslookup" the specific DNS hostname on the commandline

Nslookup -query , where is the domain name you want to look up. For example: nslookup test.local Will return the following: C:UsersUserAppDataLocalTemp>nslookup test.local Non-authoritative answer: Name: test.local Address 1: 193.188.123.25
This is because test.local has an A record that points to 192.168.100.1, which is the local DNS server used for DNS resolution on my system.
