Does TTL in reply DNS servers on the frequency of browser requests to a DNS?

do I understand correctly that the TTL in the DNS response to the browser will allow you to control the frequency of requests to DNS?
for example, the TTL for somesite.com there will be 100 seconds. if the user is within 100 seconds after the first query will not appeal to DNS, after 101 seconds will have to request the IP for a domain?

TTL in the DNS response to the browser will allow you to control the frequency of requests to DNS?

Hypothetically: Yes.
In practice:
  • Some intermediate DNS servers cacheroot response against TTL (as noticed @saboteur_kiev), but now it happens rarely.
  • Some browsers have their own caching mechanisms of the DNS.
can you give me a lead on information about "Some browsers have their own caching mechanisms of the DNS"?? - Juwan3 commented on July 9th 19 at 11:31

TTL does not affect the browser, and the DNS in General.
You have the DNS cache client OS
your DNS servers your cache
your DNS server has a DNS server that its cache
and so on to the root servers

but 100 seconds is very small, it is likely that on the way to your browser, a DNS server will not resolvida more often than xx, despite the settings of your TTL
but if you just focus on the interaction of browser and DNS. for example, the DNS server of the ISP returns a TTL = 10 sec. would that make the browser after 10 seconds again to request the IP address of the domain that the browser has just visited? - Juwan3 commented on July 9th 19 at 11:33
:
In fact, in fact, the browser doesn't know what DNS is, he always turns to driver IP Protocol, which is already working with the same /etc/hosts and DNS cache service, and accesses the DNS server of the provider.

If you don't dig deep, then Yes - every time the browser will ask where to download the data. You can experiment with the same /etc/hosts - eldon_Batz84 commented on July 9th 19 at 11:36
