I can’t seem to stop the IPv6 address being registered by our server. Does anyone know how? This is causing slow browsing issues when browsing to spiceworks server using Internet Explorer. The problem is due to Internet Explorer accessing spiceworks using an IPv6 address when it should be using a IPv4 address. I’ve followed the instructions below on how to stop IPv6 addresses being registered, but that didn’t help. How to remove or disable IPv6 [...]

I’ve a tunnel broker from he.net associate with a IPV6 /64 subnet As a newby to ipv6, i’ve just discovered that its not reliable to only set a subdomain to a AAAA entry : because most of ISP will not be able to reach it Considering i got 3 vm, each with ipv6 ip , i would like to know if there any way to set up my dns to handle that ? I only [...]

With the command like these the following you can add neighbor proxies in Linux ip -6 neigh add proxy 2001:db8:100:3022:1::4 dev eth0 Is there a way how to list which proxies have already been defined? Asked by aef Try with: ip -6 neigh show proxy It works for me: emily ~ # ip -6 neigh add proxy 2001:db8:100:3022:1::4 dev eth0 emily ~ # ip -6 neigh show proxy 2001:db8:100:3022:1::4 dev eth0 proxy Answered by mulaz [...]

I have IPv6 addresses on a Linux based server. How can I switch the current address to a new one? Is there a way to do it using shell commands? How about using Python? Thanks. Asked by Austin Modo Easy: ip -6 address add 2001:dead:beef::2/64 dev eth0. The same goes for removal: ip -6 address delete 2001:dead:beef::1/64 dev eth0 To show your addresses: ip -6 address show Answered by Falk Stern Check more discussion of [...]

I want to tar to a remote host using the remote host’s IPv6 address. I can ssh and scp to the host but GNU tar does not accept the IPv6 address. I tried: tar -cjvf root@2001:DB8::1234:5678:/backup.tar.bz2 * and tar -cjvf root@[2001:DB8::1234:5678]:/backup.tar.bz2 * and tar -cjvf root@\[2001:DB8::1234:5678\]:/backup.tar.bz2 * but none of these work. All of these give address errors from tar. My Ubuntu system has tar version 1.25-3. Asked by Lars Nordin I found the answer [...]

I have a development and a production server, both running CentOS, on the same network with similar configurations. On one (the production server), when I do a curl, it attempts IPv6 first, but that times out after around 45 seconds and falls back to IPv4, which works fine. Ping6 also times out and never receives any packets back, but regular ping (which I think goes over IPv4) works fine. On the development server, ping6 and [...]

I have a dual-stack network with a DHCPv6 server in a stateful mode (managed address configuration). Windows 7 and Ubuntu 12.04 hosts get the address configuration successfully, but still prefer the randomly generated addresses for a source address with a prefix advertised by RA. If the privacy extensions are turned of with netsh interface ipv6 set privacy state=disabled, the problem disappears and the DHCP-provided address is used as a source. I would like to know [...]

I’m trying to set up IPv6 on FreeBSD 8.2. I added to the /etc/rc.conf the following lines: ipv6_enable=”YES” ipv6_gateway_enable=”YES” ipv6_ifconfig_le0=”ff00::2″ and restarted IPv6: /etc/rc.d/network_ipv6 restart Now I have the following settings for network interfaces: le0: flags=8843<UP,BROADCAST,RUNNING,SIMPLEX,MULTICAST> metric 0 mtu 1500 options=8<VLAN_MTU> ether 00:50:56:01:04:87 inet 10.76.247.78 netmask 0xffffff00 broadcast 10.76.247.255 inet6 ff00::2 prefixlen 64 nd6 options=3<PERFORMNUD,ACCEPT_RTADV> media: Ethernet autoselect status: active le1: flags=8843<UP,BROADCAST,RUNNING,SIMPLEX,MULTICAST> metric 0 mtu 1500 options=8<VLAN_MTU> ether 00:50:56:01:04:86 media: Ethernet autoselect status: active plip0: [...]

I have an interesting problem. An ISP of ours started providing native IPv6 on their network. They provided us with a /56 prefix and a /126 linking segment (::1 being their endpoint and ::2 being ours). However, the ISP’s DSLAM does not support Neighbor Discovery, so they asked us to provide our router’s MAC address to manually enter in their neighbor table and provided us with theirs. We are using Mikrotik’s RouterOS 5.2 on our [...]

I use Ubuntu server as router, NATing router and webserver. The server is connected to ISP with a public /29 subnet. Also I host some important websites on it. I asked the ISP to provide ipv6 address block. They say that the router where my link terminates at ISP does not have ipv6 support. So they said that if I’m ready connect to their edge router via a private 172.16.x.x/30 subnet, they can provide me [...]
