domain name servers

The DNS is the service that translates a domain name into an IP address where a website is hosted. Users can set up a specific DNS on the settings of their connection (on mobile phones, tablets, laptops, etc). Here how to set up the DNS. When a DNS Server resolves a domain name, a query travels from ...

A couple of notes up front, though: Cloudflare's 1.1.1.1 DNS can also be used for encrypted DNS resolution that keeps your ISP from seeing where you go on the internet. Setting that up is immensely complicated, and running it will probably slow down your DNS queries, but if you're a veteran with the Linux ...

Like the internet itself, the directory is distributed around the world, stored on domain name servers that all communicate with each other on a very regular basis to provide updates and ... The request then goes to the Domain Name Server, which holds the information about the site and its IP address.

Those personal details are transmitted in plain text, making intercepting it easy. Internet users also need to have faith in the security of their DNS provider—all the information transmitted can be stored, creating a total profile of the internet use coming from your IP address, or even your particular computer.

DNS, as it's more commonly known, is the essentially the contact list for the internet. Just as you tap on a name in your smartphone's contact list and it dials the number without you needing to know that number, the DNS system converts the name of an internet domain or website into its numeric address.

In other words, whether you use your ISP's resolver, or one provided by a third party like Google or Cloudflare, at some point you have to trust the resolver with your DNS requests. In a world where law enforcement has taken an increasingly-intrusive attitude to Internet traffic, the authors believe DNS ...

A couple days ago, Cloudflare launched its own DNS service at 1.1.1.1, promising that consumers would enjoy greater privacy and potentially faster internet if they switched over from their ISP's default. Now, those speed differences might not be significant or noticeable enough to the point of making the ...

The killswitch uses a DNS lookup, stopping itself if it can resolve a certain domain. Manufacturing networks are largely disconnected from the Internet enough that such DNS lookups don't work, so the domain can't be found, so the killswitch doesn't work. Thus, manufacturing systems are no more likely to ...

With an increasing proportion of daily business reliant on the public internet, having effective Domain Name System (DNS) security in place has never been more important.

Mozilla's plan to test a more secure method for resolving internet domain names – known as Trusted Recursive Resolver (TRR) via DNS over HTTPs (DoH) – in Firefox Nightly builds has met with objections from its user community due to privacy concerns. The browser maker's intentions appear to be ...

NCSI performs DNS query for www.msftncsi.com. Next, HTTP contacts the website http://www.msftncsi.com/ncsi.txt. The request is sent via a plain text file with only content as “Microsoft NCSI”, thus safeguarding the privacy of user's information. Then, NCSI performs a DNS query for dns.msftncsi.com.

March has seen the first of the DNS Operations, Analysis, and Research Center (OARC) workshops for the year, where two days of too much DNS is just not ...

By DDoSing Dyn and destabilizing the company's DNS servers, attackers caused outages by disrupting the mechanism browsers use to look up websites. "The most frequently attacked targets for denial of service is web severs and DNS servers," says Dan Massey, chief scientist at the DNS security firm ...

An alarming number of organisations are still leaving themselves wide open to cyber-crime and Distributed Denial of Service (DDoS) attacks, by not prioritising domain name system (DNS) security. DNS is used by every single business on the internet, so seems perplexing that so few have full visibility or ...

When you connect to the attacker's website, your computer asks the internet where it can ask what the address of their domain is. The internet responds with “Go here and ask this server that”, with a link to the attacker's DNS server. Once that interaction happens, the attacker's server responds with the ...

The DNS, or Domain Name System, is foundational to the functioning of the Internet. Do you email? You're using DNS. Facebook? Same. When a DNS server has been rendered inaccessible by a cyber-attack, every single website that it supports is also inaccessible. Considering that companies today rely ...

In 1983 – the year the internet was born – the potential cyber attack surface consisted of a tiny 4.29 billion addresses. Now, 35 years and tens of billions of devices and websites later, Internet Protocol version 6 (IPv6) can support a baffling 340,282,366,920,938,000,000,000,000,000,000,000,000 – 340 ...

Overview — Stabilizing the domain name resolution (DNS) infrastructure is critical to the operation of the internet. Single points of failure become more consequential as a larger proportion of the internet's biggest sites are managed by a small number of externally hosted DNS providers. Providers could ...

The DDoS attack on Dyn took many major web sites offline for most of a day, including Twitter, PayPal, Reddit, Amazon, and Netflix. Millions of compromised IoT devices, belonging to the Mirai botnet, flooded Dyn's DNS service with up to 1.2 TBps of bogus traffic, making it impossible to respond to genuine ...

The world's top eight DNS providers now control 59 per cent of name resolution for the biggest Websites - and that puts the Web at risk, according to a group of Harvard University researchers. The group was led by Harvard's Shane Greenstein, and warned that since 2011, the "entropy" of the DNS (referring ...

Over the past two decades, technological developments have dramatically improved internet speeds. Back when dial-up was the standard method to connect to the internet, even waiting for a low-res image to load gave you time to go make a coffee. These days, broadband and fiber connections have ...
