When constructing the query packet, DNS lookup removes the first part of the domain name (the client host name) and replaces it with wpad. Then, it "moves up" in the hierarchy by removing more parts of the domain name, until it finds a WPAD PAC file or leaves the current organisation. The browser guesses where the organisation boundaries are.
A DNS sinkhole, also known as a sinkhole server, Internet sinkhole, or Blackhole DNS [1] is a Domain Name System (DNS) server that has been configured to hand out non-routable addresses for a certain set of domain names. Computers that use the sinkhole fail to access the real site. [2]
Pi-hole can also function as a network monitoring tool, [18] which can aid in troubleshooting DNS requests and network faults. [7] Additionally, it can enhance security by blocking malicious domains and phishing attempts, reducing the risk of malware infections on connected devices. [ 17 ]
The domain name .local is a special-use domain name reserved by the Internet Engineering Task Force (IETF) so that it may not be installed as a top-level domain in the Domain Name System (DNS) of the Internet. As such it is similar to the other special domain names, such as .localhost. [1]
Users can choose to use an already modified DNS server [63] [64] [65] or set up a dedicated device running adequate software such as a Raspberry Pi running Pi-hole themselves. [66] Manipulating DNS is a widely employed method to manipulate what the end-user sees from the Internet but can also be deployed locally for personal purposes.
The AS112 project is a group of volunteer name server operators joined in an autonomous system. They run anycasted instances of the name servers that answer reverse DNS lookups for private network and link-local addresses sent to the public Internet. These queries are ambiguous by their nature, and cannot be answered correctly.
Caching of proxy auto-configuration results by domain name in Microsoft's Internet Explorer 5.5 or newer limits the flexibility of the PAC standard. In effect, you can choose the proxy based on the domain name, but not on the path of the URL. Alternatively, you need to disable caching of proxy auto-configuration results by editing the registry.
