DNS Hosting Service FAQ
- What Is DNS?
- DNS, Domain Name System, is a set of protocols and database definitions. It is a distributed system that translates human readable hostnames to network readable IP addresses. It is comprised of nameservers, resolvers (clients), and many, many many records.
- How does DNS work?
- A computer user types a URL (also known as a Web address) into his or her web browser. That user's computer must translate the webserver's name into an IP address before it can try to connect to the web server. A 'resolver' or DNS client software on the user's computer asks its DNS server for the webserver's IP address. If the nameserver knows the answer (either it is in its cache or it is the nameserver responsible for that domain), it returns the IP address immediately. If not, the nameserver begins a recursive query to find the address. This query begins with the Internet root nameservers and involves following "Start of Authority" records through a hierarchical organization (root, top-level domain, e.g. "edu", site, subdomain, etc.) until the answer is found. The nameserver returns the IP address and caches all information learned along the way, in case other clients want the same or similar information.
- What is DNS caching?
- When you type a web address into your web browser and press ENTER, you are sending a query to a DNS server. If the query is successful, the website you want opens; if not, you'll see an error message. A record of these successful and unsuccessful queries is stored in a temporary storage location on your computer called the DNS cache. DNS always checks the cache before querying any DNS server, and if a record is found that matches the query, DNS uses that record instead of querying the server. This makes queries faster and decreases network and Internet traffic.
- How do I register a Domain Name?
- Domain names can be obtained through any reputable Name Registrar or one of their reseller affiliates. GridSouth Networks is a certified Enom reseller and can register domain names on behalf of your business. You may also register domain names directly with the registrar of your choice.
- How do I configure a domain to work with GridSouth Networks DNS service?
- Once a domain name is registered, you have a choice to use the domain registrar's default name servers or to specify custom name servers. In order to allow our DNS servers to resolve queries for your doamin name, the DNS service must be configured on our DNS servers AND you must change the name servers listed with your registrar to point to the GridSouth Networks name servers.
- How secure is GridSouth's DNS service?
- GridSouth Networks has implemented the latest DNS security protocols to protect against DNS cache poisoning, DDoS attacks and large-scale spoofing. Since DNS query results can be cached at locations along the client path, we cannot guarantee the content of DNS cache served from locations outside of our network. We do guarantee that results returned directly from our DNS servers are correct and secure.
