Just like in Mac OS X, you can change the DNS servers on your iPhone. This can significantly speed up Safari and other iPhone apps that use the Internet. For a general introduction to DNS, and to learn why you would want to change the DNS servers on your iPhone, see How to Change Your Mac's DNS Servers.

Before we start, you should know a couple things about how iOS handles DNS. First, these instructions only work for Wi-Fi connections - iOS does not allow you to change the DNS servers when connected to cellular networks. Also, the changes are network specific, so you'll need to change the DNS servers every time you connect to a new wireless network. The good news is that iOS remembers the settings, so you won't have to do anything the second time you connect to a network.

Here's how to change your iPhone's DNS servers:

1. From the iPhone's home screen, tap Settings.
   
   
2. Tap Wi-Fi. The screen shown below appears. The available wireless networks in range of your iPhone appear, as shown below.
   
   
3. Find your wireless network in the list, and then click the arrow. The screen shown below appears.
   
   
4. Tap the DNS field.
   
   
5. Delete the current DNS servers, and enter the new DNS servers. (If you enter more than one DNS server, be sure sure to separate the servers with commas.)
   • To use OpenDNS, enter 208.67.222.222 and 208.67.220.220
   • To use Google DNS, enter 8.8.8.8 and 8.8.4.4
6. Test your new DNS servers to make sure they're working.
   • If you're using OpenDNS, visit the OpenDNS test page.
   • If you're using Google Public DNS, follow these testing instructions.

That's it! You've updated your iPhone's DNS servers!

The National Research Center for Applied Cybersecurity ATHENE has uncovered a critical flaw in the design of DNSSEC, the Security Extensions of DNS (Domain Name System). DNS is one of the fundamental building blocks of the Internet.

DNS4EU to element strategii cyberbezpieczeństwa opublikowanej przez Komisję Europejską. Celem projektu jest wprowadzenie prywatnego i bezpiecznego publicznego resolvera DNS w ramach Unii Europejskiej, co przyczyni się do budowania niezależności w obszarze usług cyfrowych.

DnsEye is monitoring network traffic by capturing Domain Name System DNS packets in network and displays the host names resolve information. The program allows to monitor requested URLs in network, to open it in browser and save captured DNS name list in the file. The tool is designed with a user-friendly interface and is easy to use.

It is a very simple and fast program that easily lets you find your own IP address, resolve hostnames to IP addresses and IP addresses to hostnames using the DNS.

New ETSI White Paper on Enhanced DNS Support in Distributed MEC Environments

Sophia Antipolis, 8 September 2020

Today ETSI announces the publication of its White Paper on DNS Support in Distributed MEC Environments. DNS (Domain Name System) is a key infrastructure element in any distributed edge cloud as it is used to ensure that modern (i.e. URL/URI-based) services requests are resolved to the properly located service instances. The best instance may often be decided based on properties other than location, e.g., service latency, resource availability as well as the device identifier.

Bert Hubert, author of the open source PowerDNS nameserver discusses DNS security and all aspects of the Domain Name System with its flaws and history.

The European Union (EU) has set a high bar by tackling domain name system (DNS) abuse head on via government regulation and seems to have successfully resisted attempts to water down DNS stewardship obligations. Recent guidance from a key European Commission cooperation group (the NIS Cooperation Group) handling sections of the Network and Information Security Directive (NIS2) intends for a robust implementation of Article 28, which will go a long way toward helping to mitigate some of the longstanding problems that persist in the DNS.

As the world races towards digital transformation, the technologies we choose will have a lasting impact on our planet. Blockchain, NFTs, and other crypto assets have garnered much attention for their ability to securely and immutably store records. However, the environmental cost of maintaining these technologies is often overlooked. The energy consumption required to sustain blockchains, particularly those using Proof of Work (PoW), is enormous...

Abusive behavior that leverages the domain name system (DNS) continues to be a problem, with a reach that has been widely and credibly documented. There is little doubt that bad actors continue to use the DNS for nefarious and costly purposes. While the amendments made in 2024 to ICANN's Registry Agreement (RA) and Registrar Accreditation Agreement (RAA) were a step in the right direction, more advanced tools are needed to bring abuse rates down.

The U.S. Office of Public Affairs issued a statement on 4 September 2024 regarding the seizure of 32 websites that are believed to be part of the so-called "Doppelganger" campaign.

Phishing has been around for years, yet it still proves to be a major online threat. To continue profiting, cybercriminals must continuously adapt their techniques.

Zyxel USG/UAG/ATP/VPN/NXC series suffer from an issue where a DNS request can be made by an unauthenticated attacker to either spam a DNS service of a third party with requests that have a spoofed origin or probe whether domain names are present on the internal network behind the firewall.

A year ago, under the leadership of the Internet Corporation for Assigned Names and Numbers (ICANN), the internet naming community completed the first-ever rollover of the cryptographic key that plays a critical role in securing internet traffic worldwide. The ultimate success of that endeavor was due in large part to outreach efforts by ICANN and […]

С этого дня Mozilla приступила к переводу пользователей Firefox на использование по умолчанию протокола DNS over HTTPS (DoH). Перевод пока затрагивает только пользователей из США, предполагается провести его за два недели. Все остальные пользователи вполне могут включить DoG самостоятельно (Options -> General -> Network Settings). По умолчанию в качестве провайдера DoH предлагается Cloudflare, при желании можно переключиться на NextDNS.
