Trailhead Error: Protect Your Data in Salesforce -> Restrict Login Hours and IP Ranges

Question

I have started this challenge in 2 separate orgs - this last one is brand new. I have 2 issues that I'm getting error messages on:

1: The IP Address instructions cannot be followed: Enter these values: Start IP Address: 0.0.0.0 End IP Address: 255.255.255.255 Description: San Diego Because you get this error "Error: The range specified is too large"

2: When I try and get a verification (I saved the IP address with what I could), I get this error message: Step not yet complete in My Trailhead Playground 19 There was an unexpected error while verifying this challenge. Usually this is due to some pre-existing configuration or code in the challenge Org. We recommend using a new Developer Edition (DE) to check this challenge. If you're using a new DE and seeing this error, please post to the developer forums and reference error id: KJOGRDHB

This is a new DEV Org created for this challenge. And after I posted on the SF DEV Community, I also tried again by creating ANOTHER Playground and starting from scratch and got the same error...twice! So, I've tried in 3 separate playgrounds :(

Any ideas on how to overcome?

Cheers, Nat

According to salesforce help docs, it says The start and ends IP addresses must be in an IPv4 range and include no more than 33,554,432 addresses (225, a /7 CIDR block) for Organization.

you can set login IP range from 0.0.0.0 to 255.255.255.255 for profile but not for Organization level.

As per trailhead, it is asking to Restrict the Login IP Range on the Custom: Support Profile. Go to setup, search for profile and select it. click on the profile name called custom: Support profile. Under Login IP Ranges, click New and enter the details.
