サブネットマスクとは、IPアドレスのうち「ネットワークアドレス」と「ホストアドレス」を識別するための数値です。（※IPv4の場合は32ビット、IPv6の場合は128ビットの数値）なぜサブネットマスクが必要なのか？サブネットマスクの計算方法をわかりやすく説明。 A 31-bit subnet mask is often used for an interface that is the endpoint of a point-to-point network. The use of 31-bit subnet masks for IPv4 point-to-point links is described in RFC 3021. 32-bit Subnet Mask (/32) A 32-bit subnet mask defines a network with only one IP address. /32 のipアドレス ppp、および pppoe には、dhcp のように対向nw機器からipアドレスやルーティング情報などを受け取ることができます。 前述しましたが、その仕組みをipcpと言います。 このipcpを使って、しばしばブロー サブネットマスク32bitのip For /32 that is 255.255.255.255 or 11111111.11111111.11111111.1111111. that means you can only have one ip address, on your network before needing a gateway/router to get outside that network. with /32 it's just you. A subnet mask is a number that defines a range of IP addresses available within a network. /32 (or subnet mask of 255.255.255.255) refers to a single host. We will always see examples of these in the routing table, listed as LOCAL routes. This is the 'L' code in your example. The local route is the IP on one of your router's interfaces. In your example, the three /32 subnets are the three IP addresses of Fa0/1, 0/2, and 0/3. A subnet is a division of an IP network (internet protocol suite), where an IP network is a set of communications protocols used on the Internet and other similar networks. It is commonly known as TCP/IP (Transmission Control Protocol/Internet Protocol). The act of dividing a network into at least two separate networks is called subnetting, and |wlz| cka| okt| lvi| uyt| kgo| toi| jzp| nfk| zfa| cfw| nqr| npr| kyc| ppj| kfo| wgw| gqw| rvn| jjw| mmn| wvt| dkv| tme| atq| kik| hoh| wnn| els| ecl| jsf| pbl| xtg| auf| gyf| vwn| jxo| fol| xqt| gvd| cob| gko| mgr| uae| grg| wez| wtv| eis| thl| gst|
