In addition to what others have already posted, I suspect that this might be an attempt to evade spam/phishing filters that are looking for an IP address with a specific regular expression. Having a fake IP address that doesn’t match the traditional ^((25\[0-5]|(2\[0-4]|1\d|\[1-9]|)\d)\\.?\b){4}$ format might let this message slip through.
