Basically Itanium requires all the code for Windows to be re-complied. So Microsoft ported some of the roles and not other over to Itanium. I guess if Itanium got more market share they may have ported it.
Trying to understand the following I have read: "The names in the DNS form a hierarchical tree structure; this is called the domain namespace.". Can someone explain it? Which is the difference between name space and FQDN?
The naming system on which DNS is based is a hierarchical and logical tree structure called the domain namespace . Organizations can also create private networks that are not visible on the Internet, using their own domain namespaces. The FQDN is the Fully Qualified Domain Name and is specific to devices and entities WITHIN the Domain Namespace. A fully qualified domain name, sometimes also referred to as an absolute domain name, is a domain name that specifies its exact location in the tree hierarchy of the Domain Name System.
@@itfreetraining thanks a lot for the videos ! so for an AD domain of itfreetraining.com, do I need to create a zone and records at all in DNS? Confused about the AD domain called itfreetraining.com, and the DNS private zone itfreetraining.com. What records if at all I have to create would they be?(in DNS)
@@bhakta_rg When you install AD it will create a DNS zone for you or you need to create one in advanced. This will hold all the AD DNS records. If you want to call your internal and external DNS name the same then you should split your DNS zones up. This video talks about that. ua-cam.com/video/55YONDU22qc/v-deo.html
+joutiar ghaderyan The DNS server needs to contact the root hint server to find the IP Address of the .com server. This allows extra domains to be added later. For example, if they wanted to add .apple
The hostname is part of the fully qualified domain name by design, the FQDN is basically the full and formal name of the destination. A fully qualified domain name (FQDN), sometimes also referred to as an absolute domain name, is a domain name that specifies its exact location in the tree hierarchy of the Domain Name System (DNS).
Gagandeep Makkar The original DNS protocol is limited to 13 root servers. There are however a lot more of these on the internet. So thus when you configure DNS you are limited to 13.
Gagandeep Makkar Nice observation, i took the liberty on look it up, Source, Wikipedia:The use of anycastaddressing permits the actual number of root server instances to be much larger, and is 504 as of 10 October 2014
This is a quite a common misconception. The DNS protocol has a limit of 13 root server in the protocol. There may have been only 13 root servers in the world once, however now days there is a lot more than 13. So essentially DNS is limited to choosing 13 of the ones available. In operating system like windows, 13 DNS servers are chosen for you by default.
Thank you very much for these videos you put out. It has really helped me a lot and has given me deep understanding of the technology.
+Felix Mintah You're welcome. Thanks for watching!
On a site like www.nike.co.uk is the .co a secondary level or is it in the same level as .uk in the top level ?
Thanks for your support
Hi, any reason why the DNS can't be installed on the Itanium edition? Thanks!

Just to clarify... the domains found in the namespace are not at all related to Active Directory domains, correct?
Not in the case of DNS, they relate to the relative domains in DNS.
Thanks! ;)

Hi. Thanks for explanation. Why the DNS server didn't contact the .com server first ? why root hint ?

Thanks a lot. It makes more sense.
+joutiar ghaderyan You're very welcome. Glad we were able to help.
have you upload any video regarding proxy server?
can someone tell me why do we need to put the hostname for fqdn

There are 13 root servers. You said there are 300 root server. Can you explain?

Great concise explanation! Thanks!
Thank you for your great feedback!
I'm a tad bit confused...is the namespace basically the domain name?
***** The namespace is part of the domain. For example, com. edu, au are top level namespaces.
what is DNS client and how to implement?
DNS is a service installed on servers such as Windows. It can be implemented through the Server Manager "Add Features".
Very helpful, thank you!
Glad it was helpful!
Another very helpful video. Thanks.
