Is it possible to whitelist domains in ServiceNow instead of IP addresses?

[Santosh70]

Hi All,

Need your expertise inputs on the below:

we have Cloud based application which needs to be integrated with servicenow (to make REST calls for creating incidents) and cloud app IP dynamically changes.

we have IP restrictions on our instance, no matter which IP addresses we whitelist, the integration will stop working when the app servers IP addresses change. 

Is it possible to whitelist domains in ServiceNow instead of IP addresses? if whitelist for domain is not supported, any alternative approach we can take?

Thanks in advance.

Hi Santosh

This is good that IP Changes but There must be some range correct.

If i take an example of Service Now There are two IP one on which Service Now URL Resolves and Other is a range of IP thru which connection goes out from Service Now DC for Integration (VPN or No VPN).

Have checked with vendor that when your SAAS solution Hits for Outbound there must a definite Range from there DC or Cloud what ever you say.

Hi Rahul,

True. But in our case, vendor for the cloud based app was not ready to share the subnet range due to security reasons.
