Reset/Remove restricted ip access to sharepoint online

Hello,

I have set restricted ip access to my sharepoint website, and added my ip in list of allowed ip address. according this document - https://support.office.com/en-us/article/control-access-to-sharepoint-online-and-onedrive-data-based-on-defined-network-locations-b5a5f1f1-1174-4c6b-91d0-9273a6b6971f

Now problem is my ISP changed my ip address, Now even being administrator of my office 365 tenant I am not able to access my sharepoint website. Is there any way to overcome this issue?

Regards,

Ashish
