Depending on the feature set of the Registrar you're using, it may be advantageous to host your DNS elsewhere.
If for example you require Dynamic DNS services (DNS records that are updated automatically when a destination's IP changes), or wildcard DNS (allowing <anything>.yourdomain.com to point to a certain IP), many Registrars do not offer these ...

You should host your DNS elsewhere. It will save your behind when you switch registrars, it will allow you to control TTLs like crazy so you actually have close to 0 perceived downtime for users when you change hosting, etc.
I personally recommend DNS Made Easy. Have been with them for about 3 years now and they rule (at their price point).

If your site gets big enough where it's a problem (or your registrar sucks enough where it's a problem) then you should host DNS servers with another company. One that is known for such things.
Otherwise, stay with the hosting provider.
Hosting providers (especially the inexpensive ones) don't put the same effort into DNS as the companies that Do It For ...

Registrars and DNS servers for DNS management use a zone file which keeps all your DNS records for things such as A and AAAA records. Zone files are naturally unrestricted in the amount of information they can hold.
However....
Some registrars have limits within their standard DNS management and require users to upgrade to a premium/pro DNS manager which ...

It will remain fr.somewhere.com unless you have rewrite conditions configured correctly:
RewriteCond %{HTTP_HOST} =fr.somewhere.com
RewriteRule ^(.*)$ http://www.somewhere.com/$1 [R=permanent,L]
I have a cname record created for blog.legoservices.com which just points to tumblr, but all you see is blog.legoservices.com.

If your hosting account is configured to use the domain site.com (presumably specified when you setup the hosting account), then you just need to change the NAMESERVERs at your domain registrar to point to your hosting provider (ie. change ns.a.com to ns.b.com).
The DNS will then be handled by your hosting provider, which should already have been configured ...

It will change for sure -- it just can take up to 48 hours for changes to propagate (you have to check TTL (time to live) value for your DNS records).
Most likely you (your computer) still see the old cached details. When cache will expire you will get proper up-to-date details.
When you accessing it via mobile device/another country, these details were ...

One advantage of using the name servers from the registrar is that they are very highly distributed, and that can effect the speed of lookups and global propagation.
For instance, Godaddy and Enom host so many domain names that the time to live of for newly purchased domains and for DNS modifications is SUPER fast.

Relocating the webserver to the US will hugely improve server response time for US users. Investing in better DNS servers will also improve response time, but only for the first request.
The following analysis shows where your speed bottlenecks are at present. (Short version: most of the 1-2 seconds is the time it takes to reach the webserver, not the DNS ...

As others have said, I'm broadly in favour of self-managing DNS on external services. I use the rather excellent Afraid.org's service and have done so for a few years - now pay for a premium package so I can set invisibility flags on some domains, and just because I like the service. I even think I'm going to upgrade to the next tier.
It's mildly cumbersome ...

There are two separate elements to make DNSSEC work.
Generate keys and sign the DNS records.
Put the hash of the key in your parent zone (.se for example.se) via the DS record.
The latter is possible with .se and a growing number of other TLDs (refer to DNSSEC deployment on wikipedia or subscribe to the dnssec-deployment mailing list).
In regards to ...

Keep in mind that after setting Wix nameservers, all the ...

You need to update your DNS records, namely the A record (assuming you're not moving the email, if so, you need to point the MX record at your new IP as well).
You can find more details (specific for GoDaddy) here http://support.godaddy.com/help/article/680/managing-dns-for-your-domain-names and assumes you're still using the nameservers on the GoDaddy ...

It will depend on your DNS hosting is done.
I personally use Zonomi. They have a DNS API. I can issue a request like https://zonomi.com/app/dns/dyndns.jsp?action=SET&name=mynewsubdomain.example.com&value=10.0.0.1&type=A&api_key=apikeyvaluehere to set the IP address for a new subdomain.

Your registrar doesn't necessarily provide the nameservers.
You can use services like Zoneedit or Amazon's Route 53 to host your zone files and then those now become the Nameservers that you must enter at your registrar's website. These services are only a few dollars per year, tops.

First check the DNS records for your domain. You need to have an A Record for both the www. and non-www. versions of the domain. Some providers will use an @ for the non-www. version.
Then check your server's host.conf file. This is where (in Apache at least) you tell your webserver where to direct traffic for various domains. If you have a directive for ...

To solve your problem, if you're using Apache, you can use mod_rewrite in this way:
Create a text file and call it .htaccess
Open the file with a text editor and write:
RewriteEngine On
RewriteCond %{HTTP_HOST} ^juve-news\.com [NC]
RewriteRule ^(.*)$ http://www.juve-news.com/$1 [R=301,NC,L]
Save the file and upload it in your website root folder

I'll try to answer as best I can, but I'm new to this site as well.
DNS servers can basically be made on 2 platforms: on Linux/Unix or on Microsoft.
I'm going to make an educated guess and say that you're more familiar with Microsoft (MS) products than Linux. If that's wrong, let me know and we can discuss something in Linux. In MS world, you could ...

You want to build a website that stores all DNS records? Well in the 90's you could have run commands such as host -l -v -t any com and get a list of all the `.com' domains along with some other information. That no longer works.
You can sign up with Verisign and purchase .com .net .org and maybe some other zone files but that's certainly not all the ...

Yes, your steps is right
I believe only your database is miseed
For email, it seems there will be no issue. But for your domain, I would recommend you to keep it with with Network Solution, you just need to point your domain to Winhost name server. The estimated downtime is about 12-24 hours.
No idea.
When you ping your domain and it shows Winhost IP ...

Yes, this will work.
If you have a database to transfer you are missing some steps. (Like backup transfer, restore and lock the old one so no more updates happen from the old site)
Since your e-mail will be handled by the same site you should see no downtime. However, if you have any SPF records you might want to make sure they are set right on both DNS ...

You need to publish those records with your DNS provider. If you don't know who this is, post your real domain in here and we can look it up for you.
Note however that not all DNS providers offer the ability to create TXT records; the only way to know for sure is to try it, or to call their support.

This sounds more serious than it may look. If it's redirecting you to a spammer's website, your site may be infected with malware. You should first browse through the configuration on the server and see what listens for mydomain.com and if it's different than www.mydomain.com. Your DNS seems okay, but the server itself may be actually redirecting your ...

Who is your hosting company? I'm familiar with hostmonster which has unlimited hosting using virtual subdomains as addon domains. I give all my clients pop3 access and if they need web access I tell them to go to http://mail.theirdomain.com/ and their emails/passwords work.
The login is their complete email address / password
Make sure they are clicking on ...

Reverse is Typically Handled by Your Provider
Whoever supplies your IP addresses (usually your hosting provider) MUST either set up your reverse DNS entries on their DNS servers or delegate authority to your nameservers.
For most VPS/hosting providers, they must setup the DNS.
This is due to how reverse DNS lookups happen.
How a reverse DNS lookup is ...

The ping time is how long it takes for a packet to travel from your computer to the domain you are pinging.
So if I ping facebook from san francisco, and hit their server in palo alto, then the ping time will be short. If i ping them from japan, the ping time will be higher because it takes time for those packets to travel. (this is a bad example since ...

/var/named/zones is where the zone files should be kept per this thread.

After some more research I have found an answer.
DNSSEC protects against DNS cache poisoning. See About the Kaminsky bug for more information.
DNSSEC seems to be an extra service provided by the registrars. At least for .se I haven't found anything about other top domains.
From DNSSEC – The path to a secure domain:
Today, .SE’s DNSSEC service is an ...

You can have all sort of fallback schemes with domains, but the name of the DNS server that the domain registrar points to is the single point of failure. Not the actual server, but the server that they say is authoritative. So I'd pick a registrar that will compensate you if they make that sort of mistake.
Having done that, you can then build in redundancy ...
