Managed DNS FAQ

Managed DNS FAQ

Q: What is Managed DNS?

A:  Short for Domain Name System (or Service), DNS is an Internet service that translates domain names into IP addresses. Because domain names are alphabetic, they're easier to remember. The Internet, however, is actually based on IP addresses. Each time you use a domain name, therefore, a DNS service must translate the name into the corresponding IP address.

Q: Why do I need Managed DNS?

A:  LoadDNS is a carrier-class directory service that helps to accurately distribute traffic to your website. If your potential customers cannot see your website, you lose traffic, revenue, and potential relationships. LoadDNS also helps you distribute content quickly. When you update your LoadDNS account, the change is propagated throughout our network of servers allowing you to reach customers within a matter of minutes as opposed to the typical 24- to 48-hour timeframe.

Q: Is LoadDNS hard to set up?

A:  No. Once you register with LoadDNS, our easy-to-use administrative system makes setting up additional servers easy. LoadDNS's web interface is designed to take the mystery out of adding and editing your records. For most situations, all you need to know are two items--your domain name and its IP address.

Q: Is LoadDNS right for me?

A:  If you own a website, use e-mail at your own domain name, host websites, or manage services for your clients, LoadDNS is the perfect solution for you. Improve your DNS reliability and increase your DNS infrastructure without additional hardware or software expenditures. LoadDNS gives you full control and the ability to make changes and updates at Internet speed.  It is time to uncouple your DNS from your ISP or host.

Q: Does LoadDNS allow the use of DNS wildcards?

A:  While LoadDNS can certainly handle wildcards, we request that customers please take a few minutes, think their DNS needs through, and modify their DNS entries accordingly.  If you have any questions please feel free to contact our support personel.

Q: If I use LoadDNS, do I need to list you as the Technical Contact?

A:  No. Your records are meant to be handled and controlled by you. With LoadDNS, you have control of your DNS entries. List yourself as the technical contact; otherwise, you miss the whole point of outsourcing your DNS.

Q: Managed DNS is based on DNS queries. What is a DNS query?

A:  When an Internet client needs to look up a name used in a program, it queries DNS servers to resolve the name. Each query message the client sends contains three pieces of information specifying a question for the server to answer:

  1. A specified DNS domain name, stated as a fully qualified domain name (FQDN
  2. A specified query type, which can either specify a resource record by type or a specialized type of query operation.
  3. A specified class for the DNS domain name

DNS queries resolve in a number of different ways. A client can sometimes answer a query locally using cached information obtained from a previous query. The DNS server can use its own cache of resource record information to answer a query. A DNS server can also query or contact other DNS servers on behalf of the requesting client to fully resolve the name, then send an answer back to the client. This process is known as recursion.

In addition, the client itself can attempt to contact additional DNS servers to resolve a name. When a client does so, it uses separate and additional queries based on referral answers from servers. This process is known as iteration.

In general, the DNS query process occurs in two parts:

•A name query begins at a client computer and is passed to a resolver, the DNS Client service, for resolution.
•When the query cannot be resolved locally, DNS servers can be queried as needed to resolve the name.

Q: Do I have to transfer my domain name to Load just to use DNS service?

A:  No, you do not have to transfer your domain name to Load in order to use our DNS service.  Signup up for a LoadDNS package and change the nameservers to ours at your ISP or host.

Q: How long does LoadDNS take to propagate changes made to my DNS records?

A:  All changes with LoadDNS occur in real-time and are published to all servers on the network in as little as 20 seconds or whatever your TTL (Time To Live) is set at.

Q: How do I make changes to my DNS information?

A:  To make changes to your DNS settings, just login to the LoadDNS Control Panel, you will be directed to the dashboard and choose the domain name on the left hand side that you wish to edit. Use your web browser to change existing information or create new entries.

Q: How does DNS failover handle cached entries around the world? If my site fails over, will people who have been visiting my site still be able to using the new IP?

Dealing with DNS cache is challenging for a DNS failover service. Even when setting the TTL for your A record to a very low number, certain ISPs or networks will ignore those TTLs and elect to set the cache for a value that they deem appropriate.  You can't do much about this. The good news is that this really only affects a very small portion of the Internet and users who have previously cached your IP.

Q: Do you offer round-robin DNS?

A: Yes.  To take advantage of this DNS technique simply create multiple A records for your domain.

Q: Do you offer Reverse Lookup (PTR) zones?

Yes we do. You must first, however, contact the ISP that issued you your IP addresses and have them delegate the IN-ADDR.ARPA records to the LoadDNS name servers as listed in the LoadDNS admin.

Q: Why do you use our own proprietary non-BIND software?

Most managed DNS providers have implemented the Berkley Internet Name System (BIND) an “open source” DNS server application.  There have been numerous studies that show BIND DNS is the top security problem of Internet users, the problems  includes hijacking, cache poisoning, viruses and spoofing.  The implementation of our proprietary non-BIND DNS software has solved many of the above issues that come with use of BIND.  Finding a non-BIND managed DNS provider is essential.  You can have all the redundancy in the world but if your DNS gets compromised none of that will matter.  If your DNS is BIND based give our managed DNS solutions a try they all come with a 30-day free trial and a 100% SLA.

Q: Can I use the LoadDNS as a secondary server only?

Yes. By creating a zone via the LoadDNS admin that uses your own name server as the primary, you gain the benefit of our entire network.  We will be offering Secondary DNS shortly.

Q: How do I use LoadDNS with Subdomains?

Please follow these steps to perform the subdomain delegation:

    1. Create a LoadDNS Basic, Deluxe or Enterprise account:  Purchase a DNS package for the subdomain itself, e.g. subdomain.domain.com.

    2. Create an NS record:  In your current zone file for your domain at the other DNS provider, you will need to create NS (NameServer) records. These NS records "redirect" queries for the specific subdomain to  LoadDNS.  For subdomain.domain.com, these records would look like:

subdomain.domain.com.   48600   IN   NS   ns1.anycast.loaddns.com.
subdomain.domain.com.   48600   IN   NS   ns2.anycast.loaddns.com.
