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.
The authoritative DNS server is the final holder of the IP of the domain you are looking for. When you write a domain name in your browser, a DNS query is sent to your internet service provider (ISP). The ISP has a recursive server, which might have the needed information cached in its memory. But if the data is outdated, this recursive server need to find the IP elsewhere. It will try to find it in other recursive servers, but if it can’t, it needs to get the IP address from an authoritative DNS server.
You have probably seen the “https” in most of the online shops like Amazon, eBay, and Alibaba. Or maybe a green lock icon just before the domain’s name. These are clear signs that the website you are using is secure, it has an SSL certificate or a TLS one. You can safely browse it, use passwords and even pay with your credit card without the threat that someone will steal your data. The SSL certificate gives both protection and prestige to the websites using it.
The recent Black Friday we again saw the news for record-breaking revenues and profits. Over the past few years, the web has gotten faster, according to Google, 53% of users will abandon a site if it doesn’t load within three seconds. By this, you can guess that for a shopping site, the speed of the website reflects its revenue. So, we want to see whether e-commerce sites got faster as well?
The DDoS attacks are also increasing. According to Kaspersky Lab 33% of organizations experienced a DDoS attack in 2017, compared to 17% in 2016. So we also want to know if the top shopping websites are well prepared for future attacks.
In this article, we will check with our DNS tool all of the top 50 E-Commerce websites. We will see if their speed and DDoS protection is fine or they will need to improve. Based on our research we will make recommendations how these websites can improve.
DDoS Attacks are widespread threats on the internet. With the continually increasing numbers of connected devices and new innovative ways of hacking them, we can’t just stay and wait to get affected. We should smartly implement our DNS infrastructure and choose a trusted DNS provider to be safe and to evade the downtime of our services.
But to be protected, we must know the danger.
DDoS attack (denial-of-service attack). There are few different types, but in general, a DDoS attack is an attempt to overwhelm the target (a computer, few connected computers or a whole DNS network) with high traffic from multiple sources.
