Dns updating time
It needs some form of translation to make it happen, and the mechanism that enables that translation is the Domain Name System, or DNS.
You are required to have a minimum of 2 nameservers assigned to each domain name.
Their is also typically software you can place on your server to report IP changes on an automated basis. A DNS server requires such little bandwidth that their are lots of people willing to give it away.
Some of these are hobbyist sites doing it for fun and the odd donation, and other sites are commercial businesses using the service to generate traffic to sell other products such as domain name registrations, premium accounts, etc.
To use all Network Solutions® name servers, click on See More icon to the right of the name server boxes and select Network Solutions Name Servers.
When you access a website, the computer will perform DNS caching, which means that the data in the form of domain name and IP address of the website that you access are locally stored in the computer for a period of time, so when you open a web page that has previously been opened it will feel faster because the computer has remembered the IP address and it does not need to contact the DNS server.
The early Internet landscape was pretty barren with only a few hundred computers making up the ARPANET, the military/educational precursor to the Internet.
