This is excerpted from cleanfeed

The pattern defined in $Hostname is designed to match traditional hosts 
– composed of letters, numbers and dots – or IPv4 addresses.

However, IPv6 addresses, which include hexadecimal characters and the 
“:” character, do not fall into this set.

So, if an Injection-Info header contains an IPv6 address (e.g. 
“2a01:4f8:c0c:2f94::1”), the regex will not match it correctly.
