AS49544 is a network with IP addresses ranging from 195.78.108.1 - 195.78.109.255 which claims to be in the Netherlands, but may actually be in the Ukraine. The WHOIS details for the range are suspect as they refer to a domain
globalrouting.eu which actually appears to be a legitimate weather forecasting service. Everything about the domain registration details smells of a hijack.. I would strongly suggest that contacting
ipadmin@globalrouting.eu would be counter-productive in this instance, it may even be dangerous.
Out of the /23 there seem to be exactly zero legitimate sites, many of them are involved in malware distribution. It is probably worth blocking the entire IP address range. Google's
safe browsing diagnostic for the AS is damning:
