What does DNS mean?

FAq - general matters
DNS is the acronym for Domain Name System, and it is a distributed database, based on a client/server model. A DNS manages the translation of a domain name into an IP number (the so-called name resolution), and vice versa that of an IP number into a domain name (the so-called inverse resolution).

What does DNS stand for and what does it mean?

Domainland.com - Domain Name Registration and Renewal Servic...
DNS stands for Domain Name System. The DNS is a record, located at the registry, that converts IP addresses from numbers into names, i.e. 123.456.789.0 to www.yourdomain.com. This record tells a browser where your web site is located and also tells mail servers where to route your mail to. If the DNS isn't set-up properly your domain name won't work.

What does it mean when I get a DNS error?

Frequently Asked Questions
DNS is an acronym that means Domain Name Server. A DNS is similar to directory assistance with the telephone company. You give the DNS a URL (i.e. words) and the DNS converts it to an Internet Protocol (IP) address (i.e. numbers). When you get an error, it can mean a number of different things. The site's server may be unavailable, the address may be typed incorrectly, or the connection may have timed out (server did not respond in a preset amount of time).

What are DNS servers? What does it have to do with my account?

RYDIA.NET
DNS stands for Domain Name System, or a large system which answers questions about DNS lookups. If you host a domain with rydia, whenever anyone in the world punches your domain name into their browser, the browser will need to figure out what IP address our server has. So it asks its local DNS server, which doesn't know, then asks the root DNS servers, which don't know, which then ask our DNS server, which tells them what it is.

How does the DOI System relate to DNS?

Frequently Asked Questions
The most common mechanism for resolution on the Internet is the Domain Name System (DNS): http as used in URL is a use of DNS. URLs are grouped by domain name and then by some hierarchical structure, originally based on file trees, now possibly unconnected from that but still a hierarchy. DOI names offer a more finely grained approach to naming where each name stands on its own, unconnected to any DNS or other hierarchy.

What does "No results because DNS is not responding" in eMailTracker mean?

VisualRoute FAQ - integrated traceroute, ping, Whois, revers...
It is possible that eMailTracker was unable to determine the DNS servers that your computer uses. After getting this error, go into the 'Java Console' window (in the Options menu) and review the "DNS NS=" line. If empty, you can create a "dns.txt" file in the VisualRoute install folder. Place a single IP Address to your DNS server in this file and restart VisualRoute.

What does "DNS name lookup failure" mean?

Support
The DNS name lookup failure means that the first part of the URL you are requesting contains a domain name that does not exist. Double-check the address (URL) you typed to ensure it is exactly correct. This behavior occurs when the ratings system has been enabled and the Ratings.pol file is missing or damaged. Type the Supervisor password, and then click OK (if the password you typed does not work there maybe no password so delete the password and click OK).

I am getting an error about the nameserver or DNS. What does that mean?

FAQ

What does WARNING: DNS record is older than 3 hours mean?

Clam AntiVirus
freshclam attempts to detect potential problems with DNS caches and switches to the old mode if something looks suspicious. If this message appears seldomly, you can safely ignore it. If you get the error everytime you run freshclam, check your system clock. If it is set correctly, check your dns settings. If those didn’t help, try putting this at the top of your cronjob: host -t txt current.cvd.clamav.

What does the Time To Live (TTL) for a DNS record mean?

AT&T DPT Frequently Asked Questions
The TTL tells a DNS server how long it is allowed to cache a DNS record. Caching is a standard feature in the DNS. When one DNS server queries another DNS server for a record, it is allowed to store the answer in its local memory cache for the number of seconds specified by the TTL value. Only after the TTL has expired will the caching server repeat the query to get a fresh copy of the DNS record from the authoritative server.

August 2006 - My webmaster says the term "DNS' occassionally...what does that mean?

Net-to-Net, Inc
The domain name system (DNS) stores and associates many types of information with domain names, but most importantly, it translates domain names (computer hostnames) to IP addresses. It also lists mail exchange servers accepting e-mail for each domain. In providing a worldwide keyword-based redirection service, DNS is an essential component of contemporary Internet use.

Well apparently it has to do with something called gene expression, which refers to the pattern in which genes are switched on and off.
