An internal domains list can accommodate both IPv4 and IPv6 addresses, and CIDRs. This is useful when the local network contains IPv6 addresses in addition to IPv4 addresses and ensures seamless integration of Infoblox Threat Defense in the network. In addition to regular domain names, unicode domain names can also be added.</span>

> ❌ **Warning**
> ❌ 
> ❌ Do not add *infoblox.com* to an internet domain group as part of an internet domain list, if the internal domain list will be assigned or associated with an <span style="color: #000000">Infoblox </span> Endpoint group or with on-prem host. If *infobox.com* is added to an internal domain group which is assigned to an internal domain list, then the option of redirecting the domains on the internal domain list to a custom message redirect page will not be available.

## Creating Wild Card Domains

It is not required to add the wild card domain and the parent domain name to an internal domain list. By default, a domain name added to an internal domain list will be interpreted as a wild card entry, allowing resolution of both the parent domain and all its sub-domains by the configured DFP local resolvers. For example. if *test.com* is added to an internal domain list, the list can be considered to effectively include all subdomains of the *test.com* domain (corresponding to the wildcard domain *.*test.com*”).
