The Domain Name System (DNS) is a hierarchical distributed naming system for computers, services, or any resource connected to the Internet or a private network. It associates various information with domain names assigned to each of the participating entities. A Domain Name Service resolves queries for these names into IP addresses for the purpose of locating computer services and devices worldwide. By providing a worldwide, distributed keyword-based redirection service, the Domain Name System is an essential component of the functionality of the Internet.
An often-used analogy to explain the Domain Name System is that it serves as the phone book for the Internet by translating human-friendly computer hostnames into IP addresses. For example, the domain name www.example.com translates to the addresses 192.0.43.10 (IPv4) and 2620:0:2d0:200::10 (IPv6). Unlike a phone book, however, DNS can be quickly updated and these updates distributed, allowing a service's location on the network to change without affecting the end users, who continue to use the same hostname. Users take advantage of this when they recite meaningful Uniform Resource Locators (URLs) and e-mail addresses without having to know how the computer actually locates the services. Wikipedia
Time to live (TTL) is a mechanism that limits the lifespan or lifetime of data in a computer or network. TTL may be implemented as a counter or timestamp attached to or embedded in the data. Once the prescribed event count or timespan has elapsed, data is discarded. In computer networking, TTL prevents a data packet from circulating indefinitely. In computing applications, TTL is used to improve performance of caching or improve privacy. Wikipedia
What is the propagation time for DNS changes
DNS changes usually take the amount of the TTL (Time to Live) value in seconds to take effect. If you expect that you might need to make some changes, it is recommended that you lower your TTL value down to around 5 minutes (300 seconds). The most common setting is 24 hours (86400 seconds).
You should use the following for your secondary name servers in conjunction with your current primary name server(s):
- ns3.dnssvc.com 198.61.171.145
- ns4.dnssvc.com 198.61.175.93
Yes.
How do I access your API?
DNS Services' REST API documentation is available through our domain management tool.
A mail exchanger record (MX record) is a type of resource record in the Domain Name System that specifies a mail server responsible for accepting email messages on behalf of a recipient's domain, and a preference value used to prioritize mail delivery if multiple mail servers are available. The set of MX records of a domain name specifies how email should be routed with the Simple Mail Transfer Protocol. Wikipedia
All DNS Services plans are good for one year. You can log in to your account to see the expiration date, which is one year from the date of receipt of payment for services.
When you receive your annual bill, simply don't send payment. Your plan will be cancelled automatically. If you don't wish to receive any more bills, please email support@dnssvc.com.
What payment forms do you accept?
At this time, DNS Services only offers payment by check or money order.
Does my plan renew automatically?
Yes. You will receive a bill for the next year's service when the current year's service is complete. Your account will be automatically renewed upon receipt of payment.
