Hi,

Yet another quick question...

How do you decide on a domain name? I have seen some called simply "Contoso.com" some following the companies web address structure like "www.somecompany.com" etc etc

What actually decides this? Is it important?!

no nothing says you must use this or this.. contoso is a 'ms company domain name' infact if you type www.contoso.com into a web browser it will take you to the ms site! from what i gather is just best practice to name the domain something constrcutive so if there is only one domain in a companies network just call it that eg companyname .com lets say..

 

you decide, as long as it is unique and conforms to the specs.
www is a host name, not domain.

 

Domain Names usually have some relevance to the Company name.

For instance Microsoft is the company name, so they call the Domain Microsoft.com because every one knows who they are.

The importance of the name is upto the organisation it belongs to. For instance I work in a school, and our domain name is simply school.loc because that is what we are, a school. The .loc indicates that it is a local domain name not to be confused with our Web registered domain name.

 

depends. if you are strictly going to use the domain name internally, then you can choose whatever you want. call it cnn.com if you like, or google.com. it doesn't matter. if you want an internet presence, then you are restricted to what domain names are available and will suit your requirements.
sometimes the best thing to do is to split the two domain names, by using one domain name solely for internal use (companyint.com), and the other solely for external use (companyext.com).
as for who makes the choice, usually that's management as advized by info tech department.

 

am i right in assuming using the .loc is the same as using .local? or does .local have a different effect?

 

It means the same thing. You could call it school.portugal if you liked as it is of local importance only.

 

my lab's domain is "mylab.home". naturally it's not a public domain...

 

Just to add a little.

It is not a good idea to set up your internal Active Directory name-space with a domain name that is already registered on the Internet. For example d-faktor mentioned you could call it google.com. Well if you did, any internal requests that are intended for the real google.com domain would be directed to your internal DNS server as that would be authoritative for the domain. Hence you would introduce a name resolution problem.

The same can be said even if you own the domain name mycompany.com, you would not want your internal name-space to reflect this, as any DNS requests for the external company site would be resolved internally and to internal servers, not the Internet web servers.

Therefore people use mycompany.local or something similar because they know that internal DNS requests will not be confused with external DNS requests.

The only time where mycompany.com etc can be used internally, is when a company has registered a proper Internet DNS domain and they host their web site on their own network. Usually in a DMZ. It still would take some jiggery pokery to get DNS to work but it is possible.

 

Now that is a nice looking school AJ

 

Actually if you really want to be compliant with the rules and regs then have a look at rfc2606

Nowhere in there is it mentioned that .local and others are an accepted internal naming standard.
