no subnet declaration for start no IPV4 address
ipv4 TCP/IP subnet Table While subnetting might be easy enough to grasp as a concept, it can be a bit involved, and even mind-boggling in part due to the required manipulations of binary numbers. Many people understand the ideas behind subnetting, but find it hard to follow the actual steps required to subnet a network. The table bellow is intended as a quick reference and a fairly complete examp...

服务器意外断电关闭后，重新启动后，apache不能启动，出现httpd: Could not determine the server's fully qualified domain name, using 127.0.0.1 for ServerName，我修改了httpd.conf里面的ServerName,执行/usr/local/etc/rc.d/apache.sh start，出现了apache start，但是httpd根本没有起来。 我接着查httpd-error.log，有下面的记录 (EAI 7)No address associated with hostname: mod_unique_id: unable to find ipv4 address...
Ubuntu 设置ipv4 主要是编辑/etc/network/interfaces和/etc/resolv.conf这两个文件，前者设置了ip地址、网关、子网掩码，后者设置dns等属性 示例（参考http://linux.chinaunix.net/techdoc/net/2008/04/05/989425.shtml）： 1. 以DHCP方式配置网卡 编辑文件/etc/network/interfaces: sudo vi /etc/network/interfaces 并用下面的行来替换有关eth0的行: # The primary network interface - use DHCP to find ...
目前负责 ipv4的大区 whois.arin.net 美洲区 北美 whois.apnic.net 亚太区 包括亚洲和澳大利亚 whois.ripe.net 欧洲区 欧洲/中东(西亚)/北非 whois.lacnic.net 拉美区 拉丁美洲和加勒比海区域 非洲网络的IP查询也在whois.arin.net 本文来自ChinaUnix博客，如果查看原文请点：http://blog.chinaunix.net/u/28158/showart_261522.html

ipv4： 32位ip地址 20字节的包头 最大65535-20的包体 （包长字段包含包头部分） ipv6： 128位ip地址 40字节的包头 最大65535的包体（包长字段不包含包头部分） ipv4 mms最大传输应用数据 65535-40 ipv6 mms最大传输应用数据 65535-20 ipv6 当对端传来的syn中的mss等于65535时，说明使用了特大净荷选项，此时socket按照本地的mtu-40-20发送给对端，如果此值太大，会使用mtu发现功能确定较小的值。 本文来自ChinaUnix博客...
