Hi everyone, 

I need help defining the ip range ( system security - IP Address Access Control) to ensure the allow and deny range can be used in tandem. 

 

I reviewed this article to get the allow list https://support.servicenow.com/kb?id=kb_article_view&sysparm_article=KB0550613

  1. Log in using the admin role.
  2. Navigate to System Logs > Transactions (All user).
  3. Edit the filters as necessary.
  4. Click the gear symbol .
  5. In the slushbucket, add the column IP address from the Available column on the left side to the Selected column on the right side.
  6. Click OK.
  7. Click Run.
    However, this article explain to get the ip from NOW support. 

    https://support.servicenow.com/kb?id=kb_article_view&sysparm_article=KB0598826

Not sure which is correct? 

 

Also, how do I determine the deny list? 

 

Thanks so much for all the help!

Hi @Gemma4 

 

Yes, of course there is a risk. The slightest mistake could lead to you being locked out of your own instance. Even ServiceNow would then have no chance of helping you apart from setting back your instance to the latest backup.
