    Photo: VCGA 16-member insurance fraud gang in Beijing allegedly staged more than 20 fake traffic accidents involving vehicles and electric bicycles, with one member undergoing more than 20 CT scans in three months to help obtain medical proof for fraudulent claims, according to a report by China News Service, citing multiple media reports. 
The case was uncovered in April 2026, when the insurance company detected multiple suspicious claims through its anti-fraud system. The insurer found that more than 10 cases shared unusual similarities: Electric bicycle riders allegedly fell after collisions and suffered tailbone fractures, while the injured parties also came from a similar region.
Police later found that the suspects, led by a man surnamed Zhao, had allegedly formed a professional fraud ring. They chose quiet roads at night or in the evening, used their own vehicles and electric bicycles to stage crashes, or deliberately created accidents to make drivers appear at fault.
Investigators said the gang's key tactic was a "substitution trick" during medical examinations. A member surnamed Qi, who had actually suffered a tailbone injury, was allegedly used as a fake victim after staged crashes and went for CT scans to obtain medical records.
To receive a payment of 1,000 ($150) to 2,000 yuan each time he helped with the "injury verification," Qi allegedly ignored potential radiation risks and underwent more than 20 CT examinations within three months.
Police said the gang carried out more than 20 fraudulent cases between January and April, obtaining over 300,000 yuan ($44,600) in insurance payouts from six companies in Beijing. All 16 suspects have been arrested.

。无聊，研究了IPv6运营商的当前分布机制，发现了一个小问题。目前，ISP在给我们分配ipv6时，同时给两个不同网段分配ipv6地址。第一个是唯一的地址，即广域网端口地址。

二 | 此地址是唯一的，不会用于下行链路分配。第二个是前缀地址，它也是网关地址，用于将IPv6地址分配给其余设备。

三 | 根据IPv6分配规则，前缀地址必须在/60位之内。

四 | 目前，中国的运营商有两个前缀，一个是56，另一个是60。电信大部分是56台，联通移动大部分是60台。

五 | 当然，这个长度不好也不坏，不管是56还是60，你得到的剩余地址量是无穷的，即使你家里的每一个灰尘都被分配到了公网IP上。问题是，操作员只会为您分配一次前缀地址。

六 | 当路由器获得前缀地址时，其余设备将通过前缀地址向下分配剩余地址。例如，当您通过PPPoE拨号时，您将获得广域网端口的IP地址。此机制与ipv4:240e:9c:2a04:c8ad:bdd8:af0b:843b:f60/64相同。然后可以得到前缀IP地址：240E:9C:2CD3:8D00:：1/56。当您的手机连接到WiFi时，路由器将根据此前缀地址为您的手机分配剩余地址，例如240E:9:C:2CD3:8D00:XXXXXX:XXXXXX:XXXXXX:XXXXXX:XXXXXX如果您在家中只使用一个路由器，这样您的网络就不会出现问题，您的设备将通过此路由器在前缀下分配IPv6地址。问题是，如果您有二级路由器、三级路由器或更多。如前所述，运营商只会为您的网络分配一个前缀地址，也就是说，当您家中有二级或更多路由器时。无法通过连接到辅助路由器的设备访问IPv6地址。由于辅助路由器只能获取由主路由分配的IPv6地址，并且无法获取前缀地址，因此无法将地址分配给连接到辅助路由的设备。所以，家庭的朋友们，如果你的家庭是这样的，你需要注意它。当然，还有解决办法。首先，将二级路由器替换为交换模式，使主路由成为唯一的路由器，所有地址都通过主路由器分配。不要怪自己画得不好。其次，如果您确实需要两层或更多层路由器，则只能将非主路由器设置为IPv6穿透模式（passthrough），这相当于主路由器的IPv6分配，以完全工作，即仅适用于IPv6的IPv6交换机。

七 | 这两种拓扑相当于交换机，但区别在于：第一种是纯IPv4/IPv6都使用单层网络拓扑。二是IPv4采用多层网络拓扑，IPv6采用单层网络拓扑。需要，取决于他们自己的需要。最后指出，许多朋友的路由器不支持IPv6，因此无法获得IPv6地址。如果您的运营商已被分配并且Lightcat支持IPv6，请尝试此解决方案：如果使用此解决方案，则Lightcat必须具有强大的性能，否则将出现不稳定。因此，在经济条件允许的情况下，建议购买支持IPv6协议的路由器。
