什么是IP转发?
IP转发是指网络设备(如路由器)将IP(互联网协议)数据包从一个网络转发到另一个网络的过程。它通过将数据包定向到其适当的目标IP地址,实现不同网络段之间的通信。当设备转发并不属于其IP地址的数据包时,它充当网关,通常在不同子网或网络之间传递数据。
IP转发在路由器中至关重要,但也可以在计算机或其他网络设备上启用,使其充当网络之间的中介。如果没有IP转发,局域网内的设备无法与其所在网络以外的设备进行通信。

What Is BGP Hijacking? How Route Hijacks Work, Famous Incidents, and How Networks Prevent Them
BGP hijacking is the illegitimate takeover of traffic destined for IP address space, carried out by announcing routes for prefixes the announcer is not authorized to originate. Also called prefix hijacking, route hijacking, or IP hijacking, it corrupts the Internet’s routing tables themselves: networks around the world are told that the wrong party can deliver traffic for an address block, and they believe it. This makes hijacking fundamentally differentRead more Related Posts What Is BGP Hijacking?

Which RIRs Support Inter-RIR IPv4 Transfers in 2026?
IPv4 addresses may be globally routable, but transferring their registration from one organization to another is governed by Regional Internet Registry (RIR) policy. For organizations buying or selling IPv4 address space internationally, this creates an important question: Which RIRs support inter-RIR IPv4 transfers in 2026? As of August 2026, ARIN, RIPE NCC, APNIC, and LACNIC have established frameworks for inter-RIR IPv4 transfers, subject to compatibility between the RIRs andRead more Related Posts What Is BGP Hijacking?

What Is Reverse DNS (rDNS)? Why PTR Records Matter for Email, Hosting, and Leased IPv4
Reverse DNS (rDNS) is the process of resolving an IP address back to a domain name. It is the mirror image of the DNS lookups most people know: forward DNS translates a name like mail.example.com into an IP address, while reverse DNS translates an IP address back into a name. The record type that stores this answer is called a PTR record. For most of the Internet’s history, reverseRead more Related Posts What Is BGP Hijacking?
