Stack Exchange network consists of 178 Q&A communities including Stack Overflow, the largest, most trusted online community for developers to learn, share their knowledge, and build their careers. Not so often needed, be carefully with removing non existent IPv6 address, sometimes using older kernels it results in a crash. As you can see, on my CentOS 7 server, the IPv6 address attached to the ens33 network interface is fe80:fd75:7722:6480:6d8f.The same way, the IPv6 address configured to the ens37 network interface is fe80:20c:29ff:feaa:bd0e. Got questions or suggestions? Accompanying CD-ROM includes all RFC files mentioned in the book, the Linux source tree and sample protocol family module programs for running, configuring, and testing the NADA protocol family discussed in Ch. 10. flush the address list. DNS, or Domain Name System, is like the Internet's phonebook, translating human-friendly computer hostnames into IP addresses. Click on the Configure IPv6 field and verify it is set either to Off or to Link-local only. I need to apply flush-clean the arp table, and to have one option as Winsock for the case of win7 and if exist clean the register as Ccleaner, because I have the problem ;ubuntu@ubuntu:~$ netstat -natActive Internet connections (servers and established)Proto Recv-Q Send-Q Local Address Foreign Address Statetcp 0 0 127.0.0.1:631 0.0.0.0:* LISTENtcp6 0 0 ::1:631 :::* LISTENtcp6 1 0 ::1:53003 ::1:631 CLOSE_WAITHow can to resolve this case , in other case appear following: I think that need to clean , by the “listen”Proto Recv-Q Send-Q Local Address Foreign Address Statetcp 0 0 127.0.1.1:53 0.0.0.0:* LISTENtcp 0 0 127.0.0.1:631 0.0.0.0:* LISTENtcp 0 0 172.252.37.7:46799 94.31.29.192:80 ESTABLISHEDtcp 0 0 172.252.37.7:51130 91.189.94.232:443 ESTABLISHEDtcp 0 0 172.252.37.7:45273 91.189.95.69:80 ESTABLISHEDtcp 0 0 172.252.37.7:44964 149.210.134.182:443 ESTABLISHEDtcp 0 0 172.252.37.7:45270 91.189.95.69:80 ESTABLISHEDtcp 0 0 172.252.37.7:60107 64.233.176.95:80 TIME_WAITtcp 0 0 172.252.37.7:35899 216.58.219.110:80 TIME_WAITtcp 0 78 172.252.37.7:40483 216.58.219.72:443 LAST_ACKtcp 0 0 172.252.37.7:59036 216.58.219.67:80 TIME_WAITtcp 0 78 172.252.37.7:38157 64.233.185.94:443 LAST_ACKtcp 0 0 172.252.37.7:45275 91.189.95.69:80 ESTABLISHEDtcp 0 0 172.252.37.7:51127 91.189.94.232:443 ESTABLISHEDtcp 0 0 172.252.37.7:45271 91.189.95.69:80 ESTABLISHEDtcp 0 0 172.252.37.7:41876 216.58.219.68:80 ESTABLISHEDtcp 0 0 172.252.37.7:43539 64.233.185.154:80 ESTABLISHEDtcp 0 0 172.252.37.7:45272 91.189.95.69:80 ESTABLISHEDtcp 0 0 172.252.37.7:39388 24.139.135.147:80 ESTABLISHEDtcp 0 0 172.252.37.7:60106 64.233.176.95:80 TIME_WAITtcp 0 0 172.252.37.7:51131 91.189.94.232:443 ESTABLISHEDtcp 0 0 172.252.37.7:37724 216.58.219.78:80 TIME_WAITtcp 0 0 172.252.37.7:59708 216.58.219.66:80 ESTABLISHEDtcp 0 0 172.252.37.7:51586 173.194.219.95:80 TIME_WAITtcp 0 0 172.252.37.7:51128 91.189.94.232:443 ESTABLISHEDtcp 0 0 172.252.37.7:37227 216.58.219.98:80 TIME_WAITtcp 0 0 172.252.37.7:45274 91.189.95.69:80 ESTABLISHEDtcp 0 0 172.252.37.7:51587 173.194.219.95:80 TIME_WAITtcp 0 0 172.252.37.7:35809 64.233.176.94:80 ESTABLISHEDtcp 0 0 172.252.37.7:59035 216.58.219.67:80 TIME_WAITtcp 0 0 172.252.37.7:51132 91.189.94.232:443 ESTABLISHEDtcp 0 0 172.252.37.7:51129 91.189.94.232:443 ESTABLISHEDtcp 0 0 172.252.37.7:35666 216.58.219.110:80 TIME_WAITtcp 0 0 172.252.37.7:34426 173.194.219.94:80 ESTABLISHEDtcp6 0 0 ::1:631 :::* LISTENtcp6 1 0 ::1:53003 ::1:631 CLOSE_WAIT. Finally, use the systemctl command to … The different distributions only offer a function to store DNS information locally with the use of appropriate applications like nscd (name service caching daemon), pdnsd, dns-clean, or dnsmasq.If you use one of these services for caching, you have to control it from the terminal in order to clear the cache. This value defaults to the usual class A, B or C network mask (as derived from the interface IP address), but it can be set to any value. Most Linux distributions provide two major tools used for this task, namely IP and route command. In former times the kernel expired entries after some time without usage, but unfortunately, this is not done anymore and there seems to be no way to remove entries manually. ip a show eth0, “It is remarkable how easily and insensibly we fall into a particular route, and make a beaten track for ourselves” ~ Henry David Thoreau. # nmtui.

This command flushes the protocol addresses selected by some criteria. Adding an IPv6 address is similar to the mechanism of "IP ALIAS" addresses in Linux IPv4 addressed interfaces. IP is a Linux command line tool used to show and manipulate routing, network devices, interfaces, and tunnels. Both versions need to be configured separately.
