Machine info from IP address
Description
The following queries pivot from an IP address assigned to a machine to the relevant machine or logged-on users. To read more about it, check out this post: https://techcommunity.microsoft.com/t5/What-s-New/Advanced-hunting-now-includes-network-adapters-information/m-p/224402#M74. Query #1: get machines that have used a given local IP address at a given time - as configured on their network adapters.

| where Timestamp between ((pivotTimeParam-15m) ..30m) and IPAddresses contains strcat("\"", ipAddressParam, "\"") and NetworkAdapterStatus == "Up"
//// Optional - add filters to make sure machine is part of the relevant network (and not using that IP address as part of another private network).
//// For example:
// and ConnectedNetworks contains "corp.contoso.com"
// and IPv4Dhcp == "10.164.3.12"
// and DefaultGateways contains "\"10.164.3.1\""
| project DeviceName, Timestamp, IPAddresses, TimeDifference=abs(Timestamp-pivotTimeParam)
// In case multiple machines have reported from that IP address arround that time, start with the ones reporting closest to pivotTimeParam
