In order to accelerate DNS the majority of name servers on the web may cache (remember) DNS records on their own, so they don’t have to lookup records every time they might require them.
Whenever you go to a web site, it’s likely that the ISP’s name servers may remember the actual IP Address, so the next time a person (or somebody else) demands that web site, the actual IP Address could be gathered faster.
In cases like this your own ISP’s name server is utilizing a cached DNS record. It’ll make use of this cached record for some time, after which it’ll get the actual record once again. It’ll eventually once again cache the actual record and the never ending cycle will repeat.
That is why when you make adjustments for a DNS a number of people will not understand the adjustment instantly because they may be experiencing the cached record.
