First, there have been several attempts in the past by others to
convince Bram to do this.  Bram was adamant that he would not.  vim.org
is a domain, not a host, and the host serving the Vim website is
www.vim.org.  (In DNS RFC parlance, a host name is also a domain name,
but not necessarily the other way around.)

This is an organizational decision of those running the domain; there is
nothing, such as an HTTP standard, that requires or even encourages what
you are asking.  If the current Vim website managers want to make
vim.org redirect to www.vim.org, there is nothing wrong with that, but
it is entirely their decision.

I have no opinion one way or the other on this.  I supported Bram in the
past, and will support the new maintainers whichever way they go.  If
they do want to make vim.org redirect, the rest of this message is
important.

According to the relevant RFCs (1034 and 1035), a CNAME must not be used
at the apex of a zone (e.g. vim.org), so your proposed implementation is
wrong (i.e. non-compliant).

The alias (left side of the CNAME in a zone file) cannot have any other
records associated with it (e.g. it must not be the name of an SOA, MX,
SRV, or other record).

If the current maintainers decide to do this, there are a few ways, but
there is really only one viable way if they wish to keep the canonical
name of the web server as www.vim.org:

  Add an A (and possibly ) record for vim.org, and run a small
  HTTP/HTTPS server that redirects to www.vim.org.

The IP address(es) for vim.org can be the same as www.vim.org if the web
server handles virtual domains correctly.  It should respond with a
redirect (preferably 301 rather than 302) to handle browser history and
caching correctly.

If the website maintainers would like to change the canonical URI to
vim.org, with www.vim.org redirecting to that, use the above method,
just changing which host is redirected to the other.

Another way (of changing the canonical to vim.org) would be to give
vim.org the IP address(es) and have www.vim.org be the CNAME alias.
This is standards-compliant, whereas having vim.org be the CNAME alias
is not.  One problem with using a CNAME is that the web browser is
unaware of it; the DNS resolver simply returns the IP address for the
canonical name of the alias that it was told to look up.  This
effectively results in two different web sites with identical content.

Think about how your browser handles this.  If you go to
www.vim.org/about.php, and also to vim.org/about.php, the browser
considers these to be two different pages.  History and cache treat
these as different pages.

Using CNAME should be avoided when possible.  It generally has
non-obvious side effects, like the browser history and cache above.  If
you really want to have two names where one is an alias for the other,
and both hames are in the same zone, simply use duplicate A and 
records with different names and the same IP addresses.  This can have
some of the same problems as CNAMEs (e.g. if the web server serves the
same site from both names without redirection), but avoids extra DNS
traffic to resolve the CNAME and then resolve the A record for the
response.

If an alias and a canonical name are in the same zone, use multiple
address records rather than a CNAME record.

If you still think you want a CNAME record, read the above two
paragraphs again, and then reread this paragraph and follow its
directions.

Hi - It's a great news to see the www.vim.org hosted very quickly to new 
provider. Everything now works fine. But vim.org --->does not resolves 
or redirects to www.vim.org , can someone fix this by adding 1 CNAME in 
DNS ?

This should be fixed now since we have been moved to a new hosting 
provider. See the announcements on the vim_announce 
 list


the ssl cert should also work now.

so I am closing this now.

Hi - we can host the complete vim.org at Linode which is the best VPS 
providers of all for such hosting providers.

A Japanese user is reporting that instabilities have been observed with 
OSDN-hosted sites after the OSChina took over OSDN, and that many 
projects are moving over to SourceForge (or GitHub). I don't think 
SourceForge offers a type of hosting service that OSDN had 
offered(VPS?), but I guess we'll see. Aren't there other options 
besides SourceForge or GitHub for dedicated hosting?
