MICROSOFT-CORP-MSN-AS-BLOCK IP 25 hits our website in 24H

An IP address has accessed our website 25K times in last 24 hours. I am trying to figure it out if it is a MSN search engine bot or something els? – IP address blongs to MICROSOFT-CORP-MSN-AS-BLOCK

I am here to ask if it is safe to block this IP address as it does not seem to belong to Search Engine or does it ?

Thank you.
