Many protocols make use of identifiers consisting of constants and other well-known values. Even after a protocol has been defined and deployment has begun, new values may need to be assigned (e.g., for a new option type in DHCP, or a new encryption or authentication transform for IPsec). To ensure that such quantities have consistent values and interpretations across all implementations, their assignment must be administered by a central authority. For IETF protocols, that role is provided b...| IETF Datatracker
This document discusses the Border Gateway Protocol (BGP), which is an inter-Autonomous System routing protocol. The primary function of a BGP speaking system is to exchange network reachability information with other BGP systems. This network reachability information includes information on the list of Autonomous Systems (ASes) that reachability information traverses. This information is sufficient for constructing a graph of AS connectivity for this reachability from which routing loops may...| IETF Datatracker
Last month, Amazon lost control of its cloud-based IP address pool for more than three hours, which allowed cyber criminals to steal $235,000 from users of one of AWS’s customers. Using BGP hijacking, hackers gained control over a pool of 256 IP addresses. Briefly describing the BGP protocol, it is a backbone – the basis ...| research.securitum.com
