how often does the server_ip table update, if at all? I noticed some discrepancies with some of the ipv6 entries in comparison with the address's displayed when logging in with ssh TIA Jim..
This table contains IP addresses you entered in ISPConfig under System > Server IP. if there are discrepancies with your network configuration, then you probably altered your network config but forgot to alter the IP address settings in ISPConfig.
I've only deleted 1 server (ns2 in previous post) and rebuilt using same name/ip4, below is panel which hasn't been touched: --From ssh into console-- IPv4 address for enp0s31f6: 192.168.0.230 IPv6 address for enp0s31f6: 2604:3d08:a37f:c0df:56bf:64ff:fe75:4245 IPv6 address for enp0s31f6: 2604:3d08:a37f:b42d:56bf:64ff:fe75:4245 IPv6 address for enp0s31f6: 2604:3d08:a37f:737d::156a IPv6 address for enp0s31f6: 2604:3d08:a37f:c0c9:56bf:64ff:fe75:4245 IPv6 address for enp0s31f6: 2604:3d08:a37f:737d:56bf:64ff:fe75:4245 --end-- --from server_ip table-- 1 IPv4 192.168.0.230 1 IPv6 2604:3d08:a37f:c0c9::156a 1 IPv6 2604:3d08:a37f:c0c9:56bf:64ff:fe75:4245 1 IPv6 2604:3d08:a37f:afa6:56bf:64ff:fe75:4245 --end-- they don't match, I'm not runng a dhcp6 anywhere (that I know of)
The table contains what you add there. ISPConfig neither syncs it with your network config after the initial installl nor uses it to configure the network card. This is used for websites only. If there are IP addresses you do not want to need, then delete them.
The install script made those entries, just confused as to why they don't match. If I had a proper ipv6 network configured prior to installing ispc it could turn into an issue. I won't be deleting or anything but was just puzzled why.
My guess is your isp has given you ipv6 range 2604:3d08:a37f::/48 and your router probably created a stateless network and is now issueing random addresses to your server. Having multiple ipv6 addresses is normal and them changing is normal too in a stateless network. It can be up to 8 addresses per device.
dam i hate ipv6, nothing makes sense, you say /48?, just for the example I gave above, here's what I put together from the inside to out: Panel Lan: 192.168.0.230 GW 192.168.0.41 2604:3d08:a37f:c0df:56bf:64ff:fe75:4245 2604:3d08:a37f:b42d:56bf:64ff:fe75:4245 2604:3d08:a37f:737d::156a 2604:3d08:a37f:c0c9:56bf:64ff:fe75:4245 2604:3d08:a37f:737d:56bf:64ff:fe75:4245 Fw Lan: 192.168.0.41 2604:3d08:a37f:c0c9:56bf:64ff:fe74:d956/64 fe80::56bf:64ff:fe74:d956/64 Fw Wan: xxx.xxx.xxx.147 2604:3d08:2:1a:6c75:946d:2e27:ccdf/128 fe80::205:1bff:fede:5a52/64
Yes, all addresses start with 2604:3d08:a37f: and after that it is random. That's a /48 network. Very common, at least here in the Netherlands. So your router has 2604:3d08:a37f:0:0:0:0:0 to 2604:3d08:a37f:ffff:ffff:ffff:ffff:ffff available to issue (minus its own address(es).
The scary part is I have 5 separate firewalls/routers, each specific to a server (ns1,ns2,mx1,web01,webmail) & panel uses the same as ns1 (but not nat'd to outside). My ISP won't issue static ipv6 to business but will to home (wtf) so receives ipv6 via dhcp6 while my ipv4 is static
