    Managed DNS services - does it make sense?

    I run a small hosting biz (about 50-60 clients, mostly friends and non-profits with a few small businesses thrown in). I have used my own nameservers (registered at namecheap) so far and it has served me well.

    Looking to grow into a professional business and trying to differentiate myself, I am thinking of using Enterprise DNS services from dnsmadeeasy for all the domains hosted with me. Is this worth the trouble?

    I originally thought of additional nameservers using their Vanity DNS services, but the more I think, the more it seems like using dnsmadeeasy for primary dns could be a big draw with potential clients.

    What do the experienced webmasters here recommend?

    Thank you all in advance.

    Quite honestly, using your own nameservers would be the best route.

    Using a professional service would be a waste of money. If your nameservers are down, chances are your servers are down and your in deep anyways.

    A professional DNS service might pay off if you have more then one server...with just one it is a waste of money IMHO ...

    DNS is really important.

    If you don't currently feel up to becoming a dns expert then using a quality third party is a good option.

    Hopefully if you remain in the business you will become an expert eventually and you will be able to provide as good a service at less cost by doing it yourself.

    Sheps, I agree that if the server goes down, then it really doesn't matter if you have the best DNS in the world. In my case, I believe the chances of this happening is rare. I host with ServInt and haven't had any downtime in the last 18 months.

    yolau, that sounds like an interesting point to consider. Could you explain it a bit more? I have only one server at the moment.

    Luxore, I haven't had any problems with my own nameservers so far. Just looking to make it even more robust (and differentiate myself along the way). For example, if I used dnsmadeeasy.com, I would get DNS failover and global anycasting. I admit I am still in the early stages of understanding the full meaning of these things, but it sure does look a lot better than having just a couple of nameservers.

    If you have DNS servers spread out between at least 2 different facilities, I think you'll be ok without it.

    I use my box as primary and Everydns as secondary. Everydns.net is free and have multiple servers around the globe.

    You could also use your providers's vanity servers also. It's recommended to have 2-7 dns servers.

    I would suggest you to run a DNS service too on the server you have currently hosted your domains. I don't think that it is gonna be a difficult task to get this accomplished....

    Some things that might swing you one way or the other.

    1. every customer who checks their dns with dnsreports or intodns will have a red mark against the line that says "must be in different class c" unless your server placement complies

    2. you get to offload the cpu cycles and bandwidth, not much, but it is real

    3. you have zero configuration problems

    4. take a look at the technical and security as well as dns forums here, note the number of people whinging about dns problems. those are support tickets you would have to answer if you do it yourself.

    5. do you have as good tutorials and control panels as dnsmadeeasy?

    6. dnsmadeeasy also has divisions called hostingmadeeasy and domainsmadeeasy, you can guess what they do for a living.

    Having a dns server is easy. Doing dns well is hard.

    Try spending all day with a client because his google apps email won't go to yahoo email and he is using MX's in his zone pointed at google servers, and the google servers have incorrect reverse dns on them. And yahoo is very paranoid about reverse dns. And sometimes, the google dns is unresponsive. But, of course it's your fault because you are the smallest chain in the link. That's after spending all day the week before because yahoo couldn't talk to google. Other direction, same players.

    Hi,

    If your going to use managed DNS I would recommend that you use it for your business domain names and just use your own servers for your client's domains.

    While it is true that server is down it your site won't work anyway if DNS still works but having both DNS and the hosting down may extend the noticeable downtime for some clients to due caching.
    Common sense is not so common.

    This is exactly the case now.

    When you say server placement, do you mean the servers hosting the domains? All I have is one VPS. The private nameservers I use for the domains hosted on the VPS were registered through namecheap and point to two of the four IP addresses I was provided for the VPS. The domain for which the private nameservers are registered is also hosted on the same VPS. This is my current set up.

    For the foreseeable future, I am going to handle all this for my clients, so I don't think this is an issue. But, to understand this better - does having managed dns provide the ability for my clients to do it themselves? I don't see this facility with dnsmadeeasy and cPanel anyway doesn't provide this. A bit confused here.

    Agree. I have clients emailing me all the time about mails sent from their domains not reaching yahoo accounts. Many Indian ISPs have poorly configured Reverse DNS and Yahoo! simply drops these emails.

    Thanks to everyone else too.

    The very oldest rfcs say you should have your nameservers in different places, both netwise and geographically, so that no one event will bring them all down.

    Some people say this isn't important because if your dns is down the servers probably are too, but this isn't completely true. The exception is email.

    If your server or network goes missing temporarily, taking all your nameservers with it, then anyone who tries to send mail to one of your customers will get an immediate and confusing failure message.

    Then they phone the person they are trying to email and that person phones you.

    If however your server disappears momentarily, but you still have a functioning nameserver in another location, the email will be accepted from the sender and queued on their outbound mailserver until the message can be delivered (or until the retry time-out expires).

    In my opinion that's a better thing to have happen. You don't want people phoning you every time there is a net burp or you have to reboot your server.

    So despite what practically every cpanel "host" says, there is benefit to having nameservers in different places.

    Nicely put.

    I want to add a question, is there any 3rd party dns service provider which make us possible to syncronize with our cpanel server? or maybe other panel server.

    No, I mean the dns server ip addresses. To pass the test, they must be in separate class c(/24) ip networks. One test even notes if they are in different ASN's.

    No dns servers on your box means no dns servers to setup or maintain on your box.

    You would probably have less tickets to deal with if someone else is responsible for the dns. This is related to #3.

    Sorry, that was easydns.com that has the tutorials.

    BTW, with respect to what LUXORE says, some hosts find it advantageous to maintain their own sites away from the customer sites. That way, if the customer server goes down, they are still reachable for email and support tickets. If you maintain them on the same box, you could be blindsided by an outage.

    DNS Made Easy gives you an IP anycasted DNS environment. So worldwide your DNS queries will be answered quicker.
    But in the end if you are hosting just in one location then having a redundant DNS solution does not do that much in redundancy for your own hosting. It would just be one less thing to worry about and your DNS will never go down.
    People that state that DNS Made Easy is the same as if you ran DNS on own of your own VPSs or dedicated servers just have very little knowledge on enterprise DNS architectures or what they really do.
