 # Use Azure DNS to provide custom domain settings for an Azure service
 
-Azure DNS provides naming resolution for any of your Azure resources that support custom domains or that have a fully qualified domain name (FQDN). For example, you have an Azure web app you want your users to access using `contoso.com` or `www.contoso.com` as the FQDN. This article walks you through configuring your Azure service with Azure DNS for using custom domains.

+You can configure a vanity or custom domain for Azure Function Apps, Public IP addresses, App Service (Web Apps), Blob storage, and Azure CDN
 
 ## Prerequisites
 
 To use Azure DNS for your custom domain, you must first delegate your domain to Azure DNS. See [Delegate a domain to Azure DNS](./dns-delegate-domain-azure-dns.md) for instructions on how to configure your name servers for delegation. Once your domain is delegated to your Azure DNS zone, you now can configure your DNS records needed.

 ## Azure Function App
 
-To configure a custom domain for Azure function apps, a CNAME record is created and configured on the function app itself.
+To configure a custom domain for Azure function apps, a [CNAME record](dns-zones-records.md#cname-records) is created and configured on the function app itself. A CNAME record maps a domain name to another domain or subdomain. In this case, you create a CNAME in your public domain and provision the CNAME alias to be the FQDN of your custom domain.
 
 1. Navigate to **Function App** and select your function app. Select **Custom domains** under *Settings*. Note the **current url** under *assigned custom domains*, this address is used as the alias for the DNS record created.

 ## Public IP address
 
-To configure a custom domain for services that use a public IP address resource such as Application Gateway, Load Balancer, Cloud Service, Resource Manager VMs, and, Classic VMs, an A record is used.

An A record (address record) maps a domain name to an IP address. In this case, you create a new A record in your public domain and configure it to have an IP address corresponding to the public IP address of your Azure service.
