    Unblock Microsoft IP?

    Just got 2 notifications that one of Microsoft's IP has been temporarily and then permanently blocked for port scanning?

    131.107.0.114 (US/United States/tide544.microsoft.com)

    Should we unblock it?

    Quite easy to set false rDNS entries. Leave it.

    While it is easy to fake rDNS entries its not so easy to fake the owner of the IP RANGE it belongs to.

    i belive its for hotmail.

    It looks like Microsoft, but it may not really matter if you unblock it.

    Trace Routes. It appears to be sitting on Microsoft's Servers, but the pings to some of those servers are really high, so I can't tell.

    We just don't want to deny Bing or MSN search for any reason. Why have their servers been port scanning us for weeks? Whatever they did, CSF / LFD ended up blocking this IP permanently. Should we unblock?
