i have two questions along the same grounds!?

Question

when you are doing reverse ip runs or url searches what does the dns stand for...........what does it mean to "ping" someone or "ping" a domain? and when you do ping someone or somthing what is the action being taken?

Answer 1

DNS stands for Domain Name System (Service or Server) and it represents an Internet service that translates domain names into IP addresses.Because domain names are alphabetic, they're easier to remember. The Internet however, is really based on IP addresses. Every time you use a domain name, therefore, a DNS service must translate the name into the corresponding IP address. For example, the domain name www.example.com might translate to 198.105.232.4.
The DNS system is, in fact, its own network. If one DNS server doesn't know how to translate a particular domain name, it asks another one, and so on, until the correct IP address is returned.

Ping is a computer network tool used to test whether a particular host is reachable across an IP network. Ping works by sending ICMP (Internet Control Message Protocol) “echo request” packets to the target host and listening for ICMP “echo response” replies. Using interval timing and response rate, ping estimates the round-trip time and packet loss rate between hosts.

Answer 2

If you spend any time on the Internet sending e-mail or browsing the Web, then you use domain name servers without even realizing it. Domain name servers, or DNS, are an incredibly important but completely hidden part of the Internet, and they are fascinating! The DNS system forms one of the largest and most active distributed databases on the planet. Without DNS, the Internet would shut down very quickly.

Answer 3

Dns stands for Domain Name Server. When you 'ping' a domain, a signal is sent to the IP address obtained from the DNS record. This signal is usually traced as it passes from one server to another until it reaches the destination server to which the IP points.

Answer 4

DNS is Domain Naming Service which is how computers convert 200.10.15.2 into microsoft.com and vise versa. Think of ping as sonar on a submarine. You basically send out a "Hello, are you there" signal and the other computer responds "Yes, here I am". Unless of course ping is being blocked, and then you will not receive a response.

Answer 5

Just to add a comment to the previously posted information, you don't ping a domain, you ping a host.

Mexico's maximum contributing monetary aspect is funds it extremely is dispensed decrease back from the rustic by employing Mexican's right here illegally contained in the U. S.. that's like 13 Billion $$$$$ i imagine. in case you imagine about it, in case you've been raping, robbing and dominating a wide crew of people, it must be wisest to get the added inspired ones out of the county in the previous the finally were given so uninterested at the same time with your corruption, they slit your throat or became a revolt faction. deliver the hardship makers North. that is what Castro did.
