Managing and troubleshooting network connection issues

If you cannot access an IP address, KB0517267: Managing network connectivity issues contains tips and commands that can be used to help identify where the problem is occurring.
If LDAP Server connections fail and you receive a message containing the phrase "Verify server address and port are correct and accessible, the firewall may be blocking the connection from the ServiceNow instance to the LDAP URL. Follow the instructions in KB0538621: Obtaining IP and datacenter information to ensure that you have the correct details to allow the connection INTO your network. Both VPN and non-VPN IP address ranges are provided.
If you cannot resolve the issue and need to open an incident, review KB0521688: Troubleshooting Network Performance Data Collection to gather the information that ServiceNow Customer Support needs in order to help.

Do IP numbers Change?

Ip numbers will change if you request a datacenter move or ServiceNow initiates a datacenter change (extending capacity).
These changes will be communicated way in advance with the affected customers and the new ip ranges will be communicated with you in the change and updates on the change are communicated on a regular basis

It is the customer responsibility to communicate this with their vendors as ServiceNow does not have any knowledge of firewall settings of the third parties our customers work with.
