To quickly validate the new DNS forwarding setup, you can do the following:

```bash

# Test the DNS resolution
oc run --generator=run-pod/v1 -it --rm aro-ssh --image=debian
# Once you are in the interactive session, execute the following commands (replace the FQDN with yours)
apt-get update
apt-get install dnsutils -y
nslookup REPLACE.YOURDOMAIN.corp.
# Output should looklike:
# Server: 172.30.0.10
# Address: 172.30.0.10#53

# Non-authoritative answer:
# Name: REPLACE.YOURDOMAIN.corp
# Address: 10.165.5.4

# Terminate the session
exit

```
