Hey guys! I’ve been reading about DNS but i still have some questions. I’ve decided to put them in a “history” to express myself better.
Suppose i have registered the domain “ilikecats.com.br”; After that, suppose i have configured two servers i own to be DNS servers and have registered them.
First question: How exactly do you “register” a DNS server you own so the TLD DNS servers know you exist? In other words, so that when someone queries the “.com” DNS servers they will direct the query to your DNS server?
Moving on: I have then configured these two DNS servers to point the “ilikecats.com.br” domain to an ip address “x.x.x.x”. An adequate amount of time has passed and now everyone can access the website.
Second question: Suppose i change the ip address in my DNS server for “ilikecats.com.br” from “x.x.x.x” to “y.y.y.y”. If someone who has never acessed the site before tries to access it now, will they be able to? I’m thinking “yes” because there is no IP address cached on their computer, so they will have to query it directly from my DNS server, but is there another cache somewhere else that i don’t know about?
Thanks in advance!
