Quick, name the most important server in your network – Web server? Active Directory server? Mail server? Those are all important no doubt, but your DNS servers are probably the most critical to your network operations. Imagine you were traveling within a foreign country you had never visited before and the area was totally […]
DNS tunneling is a misuse of DNS. Domain Name Servers (DNS) have been called the internet’s equivalent of a phone book. Rather than remembering an IP address with up to twelve digits, you just need to know the domain name associated with the IP address. DNS tunneling attempts to hijack the protocol to use it […]
See if these steps describe the situation you are seeing: You ran a query against a DNS record (‘A’ record, for example) via your ISP (or other recursive DNS provider) and received no response (e.g. a NXDOMAIN, Non-existent domain or similar.) You realized that the record did not exist in your zone, which is why […]

The similarities Both solutions require that you tell us what the IP address(es) are for your ‘real servers’. That way we know how to alter DNS or route traffic when one or more servers go up or down. These IP addresses must be publicly accessible, not private. Also, both solutions use the same type of […]
One of the most important aspects of the Total Uptime Cloud Platform is the underlying IP Anycast architecture. Without it, we would not be able to deliver a 100% uptime SLA and the level of performance our customer’s demand. In this article, we’ll explain what IP Anycast is (just called “Anycast”) and how we […]
In the early days of the Internet, humans and other computers located the few massive interconnected computers the same way: by their numeric Internet Protocol (IP) addresses. Soon, the impracticality of memorizing all these numbers became obvious and a rudimentary naming scheme was developed. A central repository of names and their associated IP addresses was […]
