No-IP Now Offers IPv6 Dynamic DNS

No-IP IPv6 Dynamic DNS

What is IPv6?

IPv6 is an Internet addressing system that is designed to replace IPv4. It works in a very similar way as IPv4 but offers some additional benefits.  As the pool of available IPv4 addresses diminishes, there was a need to implement a protocol that offers a much larger pool of IP addresses to accommodate the ever-growing demand in the IP space.  We continue to see an increase in the number of Internet Service Providers (ISPs) that are providing IPv6 connectivity. This means that you may already be using IPv6 and don’t even know it. Under the IPv6 protocol, domain names like are changed into IP addresses via DNS as usual, but instead of the IPv4 DNS record type A, IPv6 uses record type AAAA, often referred to as “Quad-A.”  Because the adoption of IPv6 has been slow, many domains have both IPv4 and IPv6 addresses. An example for can be found below:

  • IPv4 address for is
  • IPv6 address for is 2607:f8b0:4007:80d:0000:200e

Most operating systems are dual-stacked, meaning that they support both IPv4 and IPv6 simultaneously and the system will choose which address to access.

What’s New with our Protocol?

The changes we have made to our dynamic DNS compatibility protocol allow for both A  and AAAA hostnames to be updated individually or dual-stacked.  We have also added functionality to send IPv6 updates through IPv4 systems.  By doing this, we have given developers the flexibility to offer Dynamic DNS services through their devices and software in whatever format best meets their use case. Please check out our updated integration page or contact our integration specialists to find out more about our Dynamic DNS API and how it now supports IPv6. Get started now by offering your customers DDNS with full support for A and AAAA records using our dynamic DNS API!

Need IP Detection?

If you are looking to use our dynamic DNS compatibility protocol on devices not connected directly to the internet (i.e., devices behind NAT), the router may be assigning IP addresses locally.  These DHCP events may occur without the router external IP address actually changing. In this case, we have provided an IP detection service that can be implemented to check for IP address changes on these devices to keep them connected to a hostname. To find out more, please visit our IP Detection Service page.

DoH: The Pros and Cons of DNS Over HTTPS


First things first, let’s give a little refresher of what DNS is. DNS stands for Domain Name System

DNS is like the white page directory for the Internet. You supply a name, DNS supplies a number. The name, in this case, is specifically a hostname and the number is an IP address. Without DNS you would have to remember every IP address of every website you want to visit.

IP stands for Internet Protocol. An IP address is a unique number that allows computers to locate each other on a network. The Internet is a big network and uses IP addresses to route the communication to the proper host. An IP address looks like this:

So how does it work? What happens when you type a URL into a web browser?

1. Enter Desired Domain (or website)

Alice wants to visit the website, so she types it in the address bar in her favorite web browser.

2. Computer Looks Up the IP Address

Her computer contacts her ISP to get the IP address for Her ISP’s DNS server doesn’t know the IP address, so it checks with the domain root servers.

3. Website Loads

The root servers tell Alice’s ISP the IP address of No-IP’s nameservers and her ISP looks up Her computer receives the IP address and connects to the website.

What is different about DoH and How does it work?

DoH stands for DNS over HTTPS.  The DoH protocol works much the same way as DNS in that a DNS query is sent to a DNS server to retrieve a website. However, DoH sends query information encrypted in HTTPS rather than plain text (as is the case with DNS). This protocol also works at the app level instead of the operating system level.  This allows DoH queries to be sent to a specific list of DNS servers and bypass ISP-level DNS default settings.

Google notes that “the idea is to bring the key security and privacy benefits of HTTPS to DNS, which is how your browser is able to determine which server is hosting a given website.”

What are the Pros and Cons of DoH?


  • It prevents man-in-the-middle attacks – since DNS queries are traditionally sent in plain-text, DoH can reduce the risk of man in the middle attacks where someone can see what DNS queries you are running between you and your recursive server because it encrypts your queries.
  • The encryption with DoH can protect sensitive information that DNS hijacking methodologies employ and obfuscate data that could be sniffed by third-party observers and ISPs.
  • Because DoH centralizes DNS traffic to a few DoH enable servers, load time performance is typically improved.


  • It overrides any sort of DNS filtering your network is doing to provide insight into security and your network info
  • It provides a different experience from web browsing and to the rest of your computer and network. You might have some DNS packets going to one recursive server and then some going through your network settings, so you may have a different experience from browser to the rest of your network.
  • It weakens cyber-security. By encrypting DNS queries, companies using DNS monitoring for cybersecurity measures will lose visibility into data such as query type, response and originating IP that are used to determine bad actors.


Where is DoH being used currently?

Currently, the only major browsers that are offering support for DoH are Chrome 78 or higher and Mozilla Firefox. Safari may offer DoH support in the future, but this has not been announced yet.

How does this affect No-IP services?

Long story short…this does not affect No-IP services. It actually shouldn’t really affect your Internet browsing either. If DoH does fail for any reason, your browser will just fall back to the traditional DNS lookups.

Anycast Networks: What Are They and Why Do They Even Matter?


We talk about our Anycast network a lot. With over 100 points of presence in globally redundant locations, what’s not to be proud of?

What is an Anycast network and why does it even matter?

Before we get into Anycast, let’s talk about a routing scheme called Unicast. Unicast is how most DNS networks work. An easy way to think of Unicast networks is one-to-one. Unicast is taking an IP address and assigning it to one unique nameserver. If you have the following nameservers: ns1, ns2, ns3, each one of those nameservers will be responsible for answering certain queries. If ns2 goes down due to power outage or severe weather, the server will move on to the next available unicast server. If the second server goes down due to being overloaded, your domain will be fully inaccessible.

So, what is Anycast?

If Unicast is one-to-one, Anycast is one-to-many. Anycast is taking the same IP address and assigning it to multiple locations across the network. In the same scenario as above, your website isn’t just hosted at one location (or on one nameserver), it is hosted on multiple name servers, in multiple locations. So, if one server in the Anycast cluster goes down, your website won’t go down with it. The queries will just be answered by the next server instead. It is used to help distribute traffic and query load across the entire network, so one point isn’t always doing all of the work. This helps keep the network fast and reliable. Anycast also helps to ensure that someone visiting your website from Tokyo, Japan, queries the server that is closest to their location. This helps to ensure that the website loads quickly.

Anycast helps ensure that the network is flexible and reliable. It helps the traffic find the quickest path. If one of our points of presence is having problems and we take it offline, that traffic will be routed to our next point of presence on the network that is nearby.

Outsourcing your Managed DNS for your domains to a reliable and trusted Managed DNS provider with a robust Anycast network is essential for small and large businesses.

If you depend on your website for customer leads and e-commerce, not thinking strategically about your Managed DNS network will do more harm than good.
