Cyber-threats are behind every corner. Recently we wrote about DDoS attacks, and how hackers are using your computer and many connected devices to create a network of bots who can bring down even the best-protected network. Today we will review another danger – DNS spoofing.
Do you know what types of DNS records are out there? If you don’t know them all, don’t worry, we will explain them all in brief. By identifying them, you can easily manage your DNS plan in the best possible way.
Are you a hosting provider who is searching for new ways to improve the user experience? The competition always looks like they are one step ahead and you struggle to keep up. You can’t afford to renew your equipment so often, so you are looking for another option.
Have you checked the possibility to implement Managed DNS in your hosting company?
Not yet!? Let us show you why this could be an excellent chance for you.
Can you guess what email forwards do? Yes, it is very simple, they redirect emails from one mailbox to another. Just as you can forward manually any email from your inbox to another email, email forwards can do the same but automatically.
Imagine you have several domains and emails in each, but you also have one primary email that you use for other tasks that you have. Wouldn’t it be convenient to receive all incoming messages in one place? You simply set up a mail forwards feature (a.k.a email forwarding) from your email firstname.lastname@example.org to your personal mailbox, and all of the incoming emails will be redirected to there by default.
These attacks usually use the UDP protocol. It is a simple connectionless communication model with a minimum of protocol mechanism. This means that one of the sides in the communication can send large amount to the other without restrictions. Without any confirmation and it doesn’t matter if the second side receive the data.
Due to the way the UDP protocol works, cyber-criminals use it to generate DDoS amplification attacks. The attacker sends a small UDP request with a spoofed IP address of the victim to public services.
The UDP protocol doesn’t require a connection verification between the parties. This is why the public services reply with the requested data to the IP address of the victim. As bigger is the data returned by exploited public service, bigger is the DDoS amplification factor.
Traffic director is a way to optimize and manage the traffic going to your domain by using geographical-based routing. Like this, your clients from Asia will get connected to your Asian servers; your European clients will connect to the closest servers they have in Europe and so on.
Traffic Director is a cloud-based implementation of Load Balancing (you can check our article on Load Balancing). It helps to improve the performance of your network. It can be incredibly useful for medium and large companies that need to deliver content to different parts of the world.
Some companies call this service traffic director, others global traffic director or GeoDNS director, but it is best known as GeoDNS, and that is why we use this term as the name of our service.
Transferring your domain name is a straightforward procedure. People do it for different reasons: some are not happy with their current domain register’s service, others were unpleasantly surprised by a price increase, and they decided to move to another.
Why should you move your domain name to ClouDNS
One year FREE – We offer you a one-year extension for free! You can enjoy the extra period at no additional cost. This means, if your domain registration is expiring on 26.09.2018, now the new period will be 26.09.2019.
Risk-free transfer – If the process got interrupted, something happened that stopped you from transferring your domain, or you just quit, you will get your money back. You will not suffer any downtime during this time.
Free DNS account – You can use all features of our Free DNS and easily upgrade to some of our Premium plans.
Seamless transfer – Your domain name’s name servers are not altered anytime during the transfer process Hence your domain will not face ANY downtime during this process.
There are various ways of sending data over IP – TCP, UDP, DCCP, SCTP, RSVP and more. We will focus our attention on the two that are most used – the UDP (User Datagram Protocol) and the TCP (Transmission Control Protocol).
UDP and TCP
Both protocols are used to send packets of data over the internet. They do that on top of the IP protocol, which means that they direct the packets to IP addresses. They are treated very similar on their way from the users’ computers, through the routers and all the way to the end destination.
You probably know already what is a forward DNS. It links the hostname/domain to the IP address. Now think from the opposite direction. Reverse DNS, also known as rDNS is doing the mirror action, using the IP address to find the hostname/domain. You might be surprised that this is actually needed, but it has significant application. It is very useful for e-mail verifications B2B and troubleshooting.
