If the list of Domain Names is empty, then the SIMs will be able to resolve any DNS. However, if there is at least one element in the list it will behave as a whitelist, allowing the client devices to resolve the IP address only for domain names that match any of the entries in the list.
For each entry in the list, you can define whether it includes subdomains or not.
- If an entry does not include subdomains, then the devices will be able to resolve a domain name only if it matches exactly the content of the entry i.e. “domain1.acme.com” would not match “domain2.acme.com”, “subdomain.domain1.acme.com” or “acme.com”
- If an entry includes subdomains, then the devices will be able to resolve that domain and any subdomain of that entry.
Some examples here:
| Entry | Includes Subdomains | Allows | Does Not Allow |
| acme.com | NO | acme.com
|
acme.ie
label1.acme.com label2.acme.com subdomain. label1.acme.com |
| acme.com | YES | acme.com
label1.acme.com label2.acme.com subdomain. label1.acme.com |
acme.ie |
| label1.acme.com | NO | label1.acme.com
|
acme.ie
acme.com label2.acme.com subdomain. label1.acme.com |
| label1.acme.com | YES | label1.acme.com
subdomain. label1.acme.com
|
acme.ie
acme.com label2.acme.com
