DoS attack, Teardrop or derivative, Ping of Death, strange non-DHCP IP address connected to wifi

I am not sure how much knowledge there is on this thread regarding Ping of Death, Teardrop, DoS and DDoS attacks but to me it seems there is lot of paranoia about being hacked. So I wanted to set the record straight as far as Netgear cable product go it appears that lot of the DoS entries that appear in the event logs. Upon further examination it appears that there is lot of cases where devices such as printer, mobile devices and etc. support IPv6 and lot of these devices are generating discovery packets or fragmented multicast IPv6 packets which cause the Netgear Cable firewall to belive it is being DoS’d when in fact it isn’t.

There is couple of mentions about HP printers with IPv6 support causing these issues and it seems that it does not matter whether you have a HP printer or not issue keeps happening. HP printers are not the only devices out there that send discovery or fragmented packets there is other devices that use these.  My suggestion is if you have a device that has IPv6 but it is not using it disable it, also other device that use multicast and discovery packets like Chromecast and so on should also be update as there was a recent issue with Google devices causing packet flooding issues which some routers believed to be DoS attacks.

As far as iOS devices showing IPs outside the subnet goes for example user that mentioned 128.60.129.150 according to public IP info this IP belongs to AS48 Navy Network Information Center ISP and based on the approximate location report this is approximate location of the Norfolk Naval Station so I doubt they you be hacking anyone’s cable gateway. In cases where mobile devices are reporting IPs outside of subnet goes I would check and make sure you are not connecting to any suspicious sites with your browsers, have any questionable apps, apps that mine your information and report it to public server installed or any type of malware infection if android OS is used.

As far as the issue with HP and other printers is concerned Netgear will be addressing that in the upcoming firmware releases once the firmwares have been tested and certified by ISPs of course.
