Information about DNS and network
When I check for DNS leaks on safari with private relay activated I can see my real DNS address and my provider. I can also see the DNS address of the private relay. Does this mean that my ISP can monitor my internet traffic? submitted by /u/Athelstan321 [link] [comments] Powered by WPeMatico

Hi guys, I’ve got 2 recursive DNS servers (geo-redundant – primary and secondary) with identical configurations of pdns-recursor. The primary DNS server receives packet cache hits of 71% while the secondary DNS server receives packet cache hits of 41%. Both receive similar number of queries, cache entries, hits – here’s rec_control for primary and secondary, … Read More “Packet Cache Hits percentage” »

Due to the nature of the existing setup, we’re doing delegated DNS and CNAMEs on Windows Server DNS to point certain resources at the F5 resolvers. In order to accurately do topology load balancing, we’re wanting to use the ends0/client subnet feature. However, I’m … Read More “EDNS0 Issues – Windows DNS Client (Win10)/Server (2016)” »
I want to ensure that a list of domains of API endpoints that are called randomly and sometimes infrequently are always cached locally to minimize response time in a server application. Is there a way with unbound that I can make it so unbound automatically re-fetches api1.example1.com and api2.example2.com before their TTL (time-to-live) expires within … Read More “With unbound, is there a way to ensure a specific domain is always loaded/cached locally?” »
Basically, I don’t get the difference between the two as they seem to be doing the same thing as shown in these pictures I added (image pic links – from Google).
