If you use a Libsyn Custom Domain with an A record, you’ll need to update your DNS settings to point to Libsyn’s new IP address. This update applies only to users whose custom domains are configured with an A record and helps ensure your domain continues to work correctly after Libsyn’s infrastructure changes.
There are three ways to connect a custom domain to Libsyn:
- Using Libsyn’s name servers
- Pointing an A record to a Libsyn IP address
- Configuring a CNAME record
This guide is specifically for users who configured their Libsyn Custom Domain with an A record. Below, you’ll learn how to identify whether you’re affected and the simple steps required to update your DNS settings.
The 3 Ways to Point Your Domain to Libsyn
When you setup your domain to point to Libsyn, you likely did so using one of 3 methods:
- Updating the name servers for your domain using Libsyn’s name servers
- Pointing an A record to Libsyn’s specified IP address OR
- Setting up a CNAME record
This article is aimed at those who are specifically pointing their custom domain to Libsyn using an A record.
Libsyn is currently making moves and upgrades to her network and server infrastructure, And in that process the IP address that is used for A records is changing. Anyone using an A record to point to a Libsyn IP address will need to update to Libsyn’s new IP address.
How to Update Your A Record
The old IP address is:
204.16.244.13
The new IP address to use is:
204.16.246.222
If you are pointing your custom domain to Libsyn utilizing an A record, please contact your DNS host and have that A record updated to the new IP address listed above.
Both IP addresses will remain available throughout October, 2019, after which the old IP address will be taken offline.
Key Takeaways for Your Libsyn Custom Domain
Keeping your Libsyn Custom Domain configured correctly helps ensure listeners can continue accessing your podcast without interruption. If your custom domain uses an A record, updating it to Libsyn’s current IP address is an important step whenever infrastructure changes occur. Alternatively, using a CNAME can reduce future maintenance by allowing Libsyn to manage IP address changes behind the scenes. After updating your DNS settings, allow time for DNS propagation before verifying that your custom domain is working as expected.
Frequently Asked Questions
How do I know if my custom domain uses an A record, CNAME, or Libsyn’s name servers?
Check the DNS management panel provided by your domain registrar or DNS hosting provider. An A record points your Libsyn Custom Domain to an IP address, a CNAME points it to another domain name, and name server settings are managed separately through your domain registrar rather than as individual DNS records.
Why does Libsyn recommend using a CNAME instead of an A record for custom domains?
An A record points your Libsyn Custom Domain directly to a specific IP address, so infrastructure changes that require a new IP address also require you to manually update your DNS records. A CNAME points to a hostname instead, allowing Libsyn to manage infrastructure changes without requiring updates to your custom domain configuration.
Where can I manage my custom domain settings in Libsyn?
You can manage your Libsyn Custom Domain from your Libsyn dashboard under your show’s settings. If you’re unsure where to find the option, refer to Libsyn’s latest custom domain documentation, as menu locations may change over time.
Who should I contact if my custom domain stops working?
If your Libsyn Custom Domain no longer resolves correctly, first contact your domain registrar or DNS hosting provider to verify your DNS records. If your DNS settings are correct but your custom domain still isn’t working with your Libsyn show, contact Libsyn Support for additional assistance.
How long does it take for an A record change to take effect?
DNS updates usually begin taking effect within a few hours, but global propagation can take up to 48 hours depending on your DNS provider and cached records. During that time, some visitors may still reach the previous destination while others see the updated one.
Will updating my A record affect my podcast episodes or RSS feed?
No. Updating the A record for your Libsyn Custom Domain only changes how your custom domain resolves to your Libsyn show. It does not modify your podcast episodes, RSS feed, or media files, so your podcast content remains unchanged during and after the DNS update.
