How do I disable IPv6 in ESXi 6.5?

usernameforcomm — Wed, 17 May 2017 22:27:32 GMT

I want to disable IPv6 on a host in ESXI 6.5. According to this page, I have to navigate to the Host, go to the Configure tab, expand Networking, and select Advanced. However, when I navigate to the Host, there is no Configure tab anywhere:

I found another page that says I have to navigate to the Host, go to the Manage tab, click Networking, and select Advanced. However, there is no Networking on the Manage tab:

In that Advanced settings section, none of those Keys are related to enabling/disabling IPv6.

I did find the Default TCP/IP stack screen under Networking:

But when I click on Edit settings, it shows this popup, none of which lets me disable IPv6:

You must use the shell no the web client.

Hi,

you can disable the ipv6 fro the command line

1.ssh to host on which you want to disable the ipv6

2. Use this command to disable the IPv6 esxcli system module parameters set -m tcpip4 -p ipv6=0

3. Reboot the host

Please let me know if it helps you

you can also disable using this command:- esxcli network ip set --ipv6-enabled=false

it also needs a reboot to the ESXi host.

Thank you

I cannot ssh to the host, because it shows me only an ipv6 address which does not work.

ssh: connect to host fe80::20c:fe04:8a75 port 22: Network is down

I have set it up in vm ware fusion. on the first day it showed me ipv4 + ipv6 address, so I thought it´s all good.

But what do I do now?
