It's a major extension to the TCP protocol, and historically most of the TCP changes failed to gain traction. After the initial TCP handshake, each peer may announce additional addresses (and ports) on which it can be reached. Typically, the server allows the client to reuse the server IP/port address. There are caveats though.

To communicate with us, they choose a protocol such as RTMPS (Real Time Messaging Protocol Secure), SRT (Secure Reliable Transport), or WHIP (WebRTC-HTTP ingestion protocol) that defines how their content is packaged and transmitted. Each of these protocols is a way to transmit audio and video frames with various tradeoffs.

In simple terms, Border Gateway Protocol (BGP) is the protocol that routes traffic on the Internet. During a BGP route hijack, an attacker advertises IP prefixes from an ASN that is not the normal originator. Here we have the DNS clients sending their DNS queries to the hijacked blocks advertised by AS10297.

Designed before the dawn of the commercial Internet, the Border Gateway Protocol (BGP) is a policy-based routing protocol that has long been an established part of the Internet infrastructure. This peering connection is used by border routers in one AS to “advertise” routes to border routers in a different AS (more on this below).

Unlike dynamic routes, learned through dynamic routing protocols such as OSPF (Open Shortest Path First) or EIGRP (Enhanced Interior Gateway Routing Protocol), static routes require the network administrator to specify the next hop or destination IP address. What is a Static Route? What are the disadvantages of dynamic routing?
