Recursive resolver: The local DNS resolver acts as a recursive resolver, meaning it will perform a sequence of queries to resolve the domain name fully. Step 3: Root name server query Root server query: The recursive resolver queries a root name server to find out which authoritative server is...
DoT is arguably better. It gives network administrators the ability to monitor and block DNS queries, which is important for identifying and stopping malicious traffic. DoH queries, meanwhile, are hidden in regular HTTPS traffic, meaning they cannot easily be blocked without blocking all other HTTPS...
What Is TTL? Meaning In DNS And CDN Time to live (TTL)is the length of time or “hops” that a packet may move through a network before being discarded by a router, or how long content or a query is retained in DNS and CDN caching. ...
The default weight is empty, meaning no weight is configured. The input range is 0-100. When the weight is set to 0, it means no resolution, but it is not allowed to set all weights to 0. If there are multiple resolution records with the same name after the weight is configured, ...
DNS supports hierarchical names and allows registration of various data types in addition to host name-to-IP address mapping used in HOSTS files. The DNS database is distributed, allowing it to both scale up and scale out, meaning performance isn't degraded when more servers are added....

only process one of them (50% sampling). Note that this sampling happens AFTERbpffilters and not before. if you have an issue keeping up with the volume of your DNS traffic, you can set this to something like2:10, meaning 20% of the packets that pass yourbpffilter, will be processed...
meaning if you're using the MSS (Multi-Server Setup), DA will send over the signed zone to the remote box, rather than the raw zone you'd be editing. Note, DA will also not let you edit a signed zone on a remote box because its format is fairly different and DA can't read it...

Unfortunately, criminals can abuse vulnerabilities in DNS, meaning you’ll need to be aware of possible scams via redirects, often referred to as “spoofing” and “poisoning.” To help you avoid these threats, let’s explain what DNS spoofing and DNS poisoning are and how they work. DNS ...
