barefruit.co.ukは安全ですか？

According to forums.verizon.com, unallocated.barefruit.co.uk is responsible for a "FIOS DNS hack / re-direct to barefruit.co.uk*****....causing super slow resolve times for websites, super SLOW connection times for...VPN and lack of DNS." Verizon responded that "This is expected bahavior[sic]. The Verizon Online DNS resolvers have NXDOMAIN redirection services that redirect any unknown host to a sponsored search page," and provide opt-out instructions. At barefruit.co.uk/opt-out/, more thorough instructions are provided, because "Barefruit recognises that some people - mainly technically savvy advanced users, may wish to opt-out of this service," which is "suggesting relevant alternatives as opposed to serving unintelligible error messages." They note that your new "DNS address must be hardcoded either into the network settings of your connection or on to your router." Before opting out, you may notice your machine sending info to 92.242.140.21 as often as it would to DNS - that is, alot. So if you'd like to set some firewall rules first, the IPv4 ranges (courtesy of *****) are: unallocated.barefruit.co.uk ***** - ***** barefruit.co.uk ***** - ***** Please be aware that these subnet ranges are only for these specific domains, not all of Barefruit Ltd. AS45028, and that blocking ***** will prevent access to barefruit.co.uk/opt-out/. See tcpiputils.com for more info.

this company tried to dns hijack my router for advertising purposes it was detected by my network monitor the ip address during the attack was ***** ***** but later after the attack it changed to unallocated.barefruit.co.uk with the same ip address ***** According to whois ***** ns-not-in-service. this is also known as pharming arp spoofing. if that was not a dns hijacking why use a fake web address in the first place ?
