Good morning.
Please how do I find the Host name of the DNS 200.3f0:4001:814:200e 
(Google)?
I tried ping.exe, nslookup.exe, nbtstat.exe (may be I used the wrong 
option?)

Carlos,

>Host name of the DNS 200.3f0:4001:814:200e

I'm not sure what this is, but it isn't a valid IPv4 or IPv6 address and 
can therefore not be found in the DNS (Domain Name System).

If you have a correct IPv6 address, try this web site for more info:

Hope that helps,

Andreas

Hello Andreas:
good morning.
Many thanks.
I cannot understanding what is happening.
Please, may be you want expend a little bit time for to type in the 
prompt command and see:

. ping GooGle.com you get the 			IP 2800:3f0:4001:808::200e

. ping uol.com.br you get the strange   	IP 
2804:49c:3103:401:ffff:ffff:ffff:1

. ping alaska-software.com you get the		IP 87.106.88.127
. nslookup 87.106.88.127 you get the 		DNS s18270554.rootmaster.com

. ping s18270554.rootmaster.com you get the	IP 69.172.201.153
.nslookup 69.172.201.153 you get a              DNS request time out

Nothing of the above is in any way "strange" or unusual. Not every IP
address has a reverse DNS entry. So there are IPs where you can't get a
host name.

What is the question? What are you trying to achieve? What exactly don't
you understand?

Thomas

Hello Thomas:
good morning.
Many thanks.
I would like to get the DNS if existing, preferencially equal to the 
name got from ping.exe. Please see the attach Example.exe

Could you, please, clarify for me if it is possiblet?

Hi Carlos,

use ping -a -4 to get name and ip4

I'll try to explain. 

First, there are (basically) two different types of IP Addresses, IPv4 and 
IPv6 (Internet Protocol Version 4 and 6), with the one that you are probably 
most familiar with being the 32 bit IPv4 addresses. They are usually 
displayed as 4 groups of 8-bit (decimal) numbers, separated by "." dots, 
like 127.0.0.0 or 192.168.1.1, for example. Theoretically, that gives you 
4.3 billion possible addresses from 0.0.0.0 through 255.255.255.255.

The IPv6 addresses are 128 bit numbers and can range from 0 to 3.4 x 10^38. 
They are displayed in a different way, as 8 groups of 4 hexadecimal digits, 
each group representing values of 0 to ffff (or 65535 decimal), separated by 
colons ":" (rather than dots). Leading zeros can be omitted and zero values 
can be left out, with multiple consecutive zero values indicated by "::".

So, any IP address with a colon ":" as a separator or with values greater 
than 255 or with hexadecimal letters (A-F), or with more than 4 groups of 
digits, is either invalid or an IPv6 address.

If you use a domain name to "ping" a particular IP address, your computer 
will first determine what IP address belongs to that domain name.

The nslookup command will query your computer's default DNS Name Server (or 
you can specify a different Name Server) to lookup DNS information about 
the specified domain name (or IP address).

>ping GooGle.com you get the IP 2800:3f0:4001:808::200e

This is a valid IPv6 address. I get the IPv4 address of: "74.125.196.102" or 
an IPv6 address of: "2607:f8b0:4002:80a::200e" for "Google.com", though. The 
IPv6 address that you get is for Google Argentina SRL, while mine is the 
default in the US.

>ping uol.com.br you get the strange IP 2804:49c:3103:401:ffff:ffff:ffff:1

This is also a valid IPv6 address. I get the same address for IPv6 as well 
as "200.221.2.45", when using IPv4.

To get IPv4 addresses (rather than IPv6 addresses) you could either disable 
the IPv6 protocol on your computer, make IPv4 the default, or explicitly 
specify IPv4 by using:

ping -4 hostname

to force the use of IPv4 addresses (on Windows Vista/7/8/10).

>ping alaska-software.com you get the IP 87.106.88.127

Again, this is also a valid IPv4 address. As Alaska Software hosts their 
"alaska-software.com" domain on 1&1 servers, you will find that this IP 
address also has (at least) one additional (default) DNS domain name.

>nslookup 87.106.88.127 you get the DNS s18270554.rootmaster.com

Actually, I get "s18270554.rootmaster.info" (not ".com") for this!

>ping s18270554.rootmaster.com you get the IP 69.172.201.153

That seems valid, as the two domain names "s18270554.rootmaster.info" and 
"s18270554.rootmaster.com" have two different IPv4 addresses. If you type:

ping s18270554.rootmaster.info

you will get the same IP address as with nslookup: (87.106.88.127). This 
means that the default reverse DNS for this IP address (87.106.88.127) is 
"s18270554.rootmaster.info" (which belongs to Alaska's hosting service, 
1&1), and this IP address was also registered (by Alaska Software) with the 
domain name "alaska-software.com". It might very well be associated with 
several additional domain names.

>nslookup 69.172.201.153 you get a DNS request time out

The "s18270554.rootmaster.com" domain name has a completely different IP 
address (69.172.201.153) and (probably) belongs to a completely different 
computer, one that apparently isn't configured to respond to pings, etc. 
It actually looks like that the domain "rootmaster.com" isn't registered 
or active right now, while "rootmaster.info" belongs to 1&1, as expected.

Hope that helps,

Andreas
