I have created a CNAME for www.example.com  to   example.org  I would like to create a CNAME for   example.com  to  example.org  Or, do I not need to do that?  Our former email domain rather than pointing to an IP address now needs to point to a cloud domain.

This is a  about CNAMEs at the apices (or roots) of zones   It's relatively common knowledge that CNAME records at the apex of a domain are a taboo practice.  Example: example.com. IN CNAME ithurts.example.net.  In a best case scenario nameserver software might refuse to load the configuration, and in the worst case it might accept this configuration and invalidate the configuration for example.com.  Recently I had a webhosting company pass instructions to a business unit that we needed to CNAME the apex of our domain to a new record. Knowing that this would be a suicide config when fed to BIND, I advised them that we would not be able to comply and that this was bunk advice in general. The webhosting company took the stance that it is not outright forbidden by standard defining RFCs and that their software supports it. If we could not CNAME the apex, their advice was to have no apex record at all and they would not provide a redirecting webserver. ...What?  Most of us know that  insists that A CNAME record is not allowed to coexist with any other data., but let's be honest with ourselves here, that RFC is only Informational. The closest I know to verbiage that forbids the practice is from :     If a CNAME RR is present at a node, no other data should be   present; this ensures that the data for a canonical name and its aliases   cannot be different.   Unfortunately I've been in the industry long enough to know that "should not" is not the same as "must not", and that's enough rope for most software designers to hang themselves with. Knowing that anything short of a concise link to a slam dunk would be a waste of my time, I ended up letting the company get away with a scolding for recommending configurations that could break commonly used software without proper disclosure.  This brings us to the Q&amp;A. For once I'd like us to get really technical about the insanity of apex CNAMEs, and not skirt around the issue like we usually do when someone posts on the subject.  is off limits, as are any other Informational RFC applicable here that I didn't think of. Let's shut this baby down.

I was searching for understanding what is the “www” at the beginning of so many web addresses in the Internet. I read in somewhere that “www” is called “hostname”.  The world “hostname” made me go a step further in searching, I read so many threads and articles but I am still confused about that.  So I decided to ask some related questions here to make it clear and I need solid and comprehensive answers please.   “hostname” vs. computer name: Is the “hostname” the same as the computer name, if its true, suppose that my computer is a web server and my computer name is “Robin” so is it correct to conclude that a hypothetical web site would be something like: Robin.websitename.com? “hostname” vs. subdomain: If “mail” in mail.google.com and “developers” in developers.google.com are called subdomains why is en in en.wikipedia.org called ? What is the difference between host name and subdomain? What is the relation between host name and fully qualified domain name (FQDN)? What is the “www” in URL of some web sites? As you know Google’s web address is www.google.com but we have many web sites without “www” for example: superuser.com and en.wikipedia.org. I read in this  that “www” is just a declarative thing not more and is not related to the concept of hostname. Do you verify that?

I've found a strange thing: some Stack Exchange sites have their own domain names instead of https://[site name].stackexchange.com. The websites which have their own domain names are:          Are there any parameters for allocating specific URLs to Stack Exchange sites?

I am looking to create a system which on signup will create a subdomain on my website for the users account area.   e.g. johndoe.website.com  I think it would be something to do with the .htaccess file and possibly redirecting to another location on the website? I don't actually know. But any information to start me off would be greatly appreciated.  Creating a sign up area is not the problem - I have done this many a time. I am just unsure where to start with the subdomain.

I had something set up wacky in our DNS setup which is now resolved. The remaining problem is that chrome has cached the incorrect setup. Specifically, when using Chrome http://example.com is now redirecting to https://example.com (naked domain), which is not valid/supported.  http://example.com SHOULD redirect to http://www.example.com and then force https://www.example.com. But on a handful of browsers (including mine) this doesn't happen because of some funky Chrome caching. I tried going to “Privacy -&gt; Clear Cache” but it had no effect.

I have a server at mysite.no-ip.org. Everything is working fine and I have a blog and owncloud that I access writing mysite.no-ip.org/blog and mysite.no-ip.org/owncloud. Now, I want to create subdomains so that I can write blog.mysite.no-ip.org and owncloud.mysite.no-ip.org.  I have looked a lot into it and the simplest tutorial was this one which I followed.   Except that I am not on my server but ssh into it remotely so if I use localhost I cannot see if this works I believe. This is my first obstacle, can I follow this tutorial without being present next to the server?  I also just discovered CNAME records which (I am not completely sure) seem necessary to what I want to do. I use no-ip.org and I have tried to follow something like this but this is not really clear either   Does anyone have any pointers? This is quite shady to me and I have no idea if I am far from the solution or really close (at least if I could try localhost that would be a first step in order to check my Apache conf but I can't even do it since I ssh).  Anyways, thanks for your help in advance. Any help, link is welcomed.

We are changing domain name but the website is staying exactly the same. We are 301 redirecting every page.  We believe that we wouldn't have to create a new property in analytics or tag manager as everything is the same but the domain name.  In Search Console would we not just use the change of address tool?

Getting the subdomain from a URL sounds easy at first.  http://www.domain.example   Scan for the first period then return whatever came after the "http://" ...  Then you remember  http://super.duper.domain.example   Oh. So then you think, okay, find the last period, go back a word and get everything before!   Then you remember  http://super.duper.domain.co.uk   And you're back to square one. Anyone have any great ideas besides storing a list of all TLDs?

I use my own domain for email, so that I can use multiple email addresses when shopping online, subscribing, etc.  These are all redirected to Gmail.  I have created some addresses under that domain for use when sending in Gmail.  What I would like to do is send mail without the need to register each address separately, or create a new email address in "Google Apps for your domain".  Is there a method to register the whole domain with Gmail so that I can send email in this way without needing to verify a new address?  [Original answers suggested Google Apps for your domain.  I didn't known about this, and I think it will be useful for me, but it doesn't obviously allow this feature.]

Is it possible to set a DNS record to redirect all example.com/* traffic to www.example.com/*?  I'm running a  app on Heroku's .  I set up , and the documentation discusses . I also read about how to do this with . However, I'm wondering if there's a way to do this via DNS, i.e., without hitting my app.

I've just read  which essentially says that when I set up DNS for example.com, the root record can't be a CNAME, it has to be an A record.  My question is, why?   I'm sure the clever people who designed DNS didn't make arbitary restrictions for no reason, but I don't see what we gain by requring root domains to be A records. I would love to just point my example.com domain to someserver.somewebhost.example and forget about it, but I can't.  Please enlighten me, billpg.

I'm trying to understand how web services which have you setup CNAME records on your domain pointing to their servers work.  For example, following the instructions on LaunchRock (), I create a CNAME record as  signup.mysite.com    with the value   sites.launchrock.com   I understand that folks accessing signup.mysite.com would be redirected to sites.launchrock.com, but I'm trying to understand how sites.launchrock.com is configured so that it detects this incoming request and tailors the webpage appropriately for my landing page.  What software / configuration is present there that handles this properly?  I looked at this  - but this did not explain how to serve different content to different domains.

My VirtualHost config is below:  &lt;VirtualHost *:80&gt;           ServerName www.example.com           ServerAlias example.com           DocumentRoot /var/www/example/html &lt;/VirtualHost&gt;   I want to add a subdomain as such: new.example.com  And I want to add a wildcard to catch all other subdomains (*.example.com) and route them to www.example.com.  How should I add this subdomain? Will it involve an A record?  For the wildcard, if I change my ServerAlias to...  ServerAlias example.com *.example.com  ... then will it interfere with my subdomain (new.example.com)?  EDIT: I have several domains on a single host (via virtual hosts). This is in the same folder as 000-default.conf, but it's named example.conf. (I've actually deleted 000-default.conf, and used conf files named after the domains they point to.)

Will transferring a domain name to a new host cause downtime at all on the domain?  It's the highest traffic time of the year for us but we really want to keep things moving and need to migrate hosts because our current host charges per subdomain. It's imortant we get this subdomain up and running in the next few weeks, so I'm wondering what kind of down time (if any) we should expect migrating the registrar.  It doesn't seem like it would...

For example, in the past, links to www.example.com wouldn't have meant Google would pass any value to say, forum.example.com. What is the current status of this? (Please provide a reference if possible).

I have to choose between my keyword + an uncommon TLD and my keyword with a prefix/suffix + .com. In general, is there a difference for SEO? I think some TLDs like .co are confirmed to rank lower.  For example, if my target keyword is example, is example.info or the-example.com better?

I am using my domain example.orgin my firm. I can use www.example.orgto view my website. If I try http://example.org from outsite my firm there is no problem, but if I try it from inside, my windows DNS servers deliverthe IPs of domain controllers.  How can I solve this? Can I prevent my DCs from registering as example.org in my DNS and will this be a problem for my enviroment?
