The default pfSense® software installation assigns the 192.168.1.0/24 address space to the LAN interface, but RFC 1918 also defines other CIDR ranges for private use:10.0.0.0/8 172.16.0.0/12 192.168.0.0/16As a general rule, it is good practice to prevent network traffic intended for RFC ...
The basic IPv6 address range an ISP allocates for a private network is large enough (currently /48) for most of the medium and large enterprises, while for the very large private enterprise networks address ranges can be concatenated. The goal of this assignment mechanism is to decrease the ...
This memo contains a snapshot of the state of standardization of protocols used in the Internet as of July 22, 2004. It lists official protocol standards and Best Current Practice RFCs; it is not a complete index to the RFC series. The latest version of this memo is designated STD 1. Ta...
多宿主是许多互联网站点服务的重要组成部分。当前的IPv4多主实践已添加到无类域间路由(CIDR)体系结构[RFC1519],该体系结构假定可以根据客户和服务提供商的层次结构聚合路由表条目。 Multihoming is a mechanism by which sites can satisfy a number of high-level requirements. It is widely used in the IPv4 In...
这意味着站点必须能够在多个无类别域间路由(CIDR)前缀[18]下运行和/或随时更改其CIDR前缀。不幸的是,IPv4的设计并不是为了促进这两种策略。但是,如果站点通过NAT盒连接到其ISP,则只有这些盒需要处理多址和重新编号问题。 Similarly, if two enterprise IPv4 networks need to be merged and RFC 1918 addresses are...
一致性的一个具体情况是IPv6唯一本地地址(ULA)[RFC4193]和IPv4专用地址[RFC1918],它们不通过“魔术”提供任何安全性。在这两种情况下,边缘路由器必须应用严格的过滤器来阻止这些私有地址进入和离开网络,同样重要的是。这种过滤可以由企业或ISP完成,但谨慎的管理员更愿意在企业中完成。 IP...
