DNS Proxy Services: Cryptographic Resolution and Privacy Protection

When Your Internet History Becomes a Public Diary

Recently, Mr. Zhang found a strange thing, he just searched for a razor on a shopping website, and then an advertisement popped up when he swiped the video. This is not the first time that this kind of "coincidence", as if someone is peeping at his screen from behind. In the end, it's a common DNS query that's running around naked - every time you visit a website, your device sends a DNS query to the operator's server.plaintext string, as if the diary was spread out on the side of the road.

The traditional DNS workflow looks like this: device->carrier server->website IP. this process.What site did you check and when?, all remembered clearly at the operator. Worse, some public WiFi will intentionally tamper with DNS records and divert your Taobao access requests to torrents.

Putting a cloak of invisibility on DNS queries

This is where DNS proxies come into play. The principle is particularly simple: add a relay station between your device and the target website. Take ipipgo's proxy IP service as an example: when you want to visit tao.com, the request will first be transmitted to ipipgo's DNS proxy server through an encrypted channel, and then they will complete the subsequent query instead of you.

 Common DNS query
Your computer -> 8.8.8.8:53 (plaintext query for "tao.com")

 Proxy DNS lookup
Your computer -> ipipgo proxy node (encrypted transmission) -> 8.8.8.8:53

There are three major benefits to doing so:
1. The operator can only see that you are connecting to ipipgo's servers, and does not know the specific content of the visit
2. Full data encryption to avoid tampering by intermediaries
3. can automatically select the optimal resolution node, speed up the opening speed of the site

Hands-on DNS proxy setup

Take the windows system for example, the service setup with ipipgo is just three steps:

1. Log in to the ipipgo console to get a dedicated DNS address (e.g. 45.76.102.88)
2. Open Network Settings -> Change Adapter Options
3. In the IPv4 properties, change the DNS server address to the IP you just memorized.

Android phones are even easier, modifying the DNS servers directly in the WiFi advanced settings. Apple users should note that iOS requires a description file to be installed in order to modify the global DNS, but using the ipipgo provided by theMobile-specific proxy toolsIt will be more convenient.
