Chrome has anonymized local IP by default. Currently have to be used different regexp to get the anonymized local IP address for chrome.
/^ |((?:[0-9A-Za-z]{1,8}))-((?:[0-9A-Za-z]{1,4}))-((?:[0-9A-Za-z]{1,4}))-((?:[0-9A-Za-z]{1,4}))-((?:[0-9A-Za-z]{1,12}))*.((?:[0-9A-Za-z]{1,5}))| $/
Pull those changes to imprint.js and imprint.min.js files
