Noooooooooo 😃  
Remove that again.  
Copy the whole lot to a text editor first and replace network details like IP address and netmask.  
After, you copy the whole lot to clipboard, and paste into SSH session + ENTER.

After the ifup command, you can check with:

`ip addr show`

so, i have ran through that mini guide and seem to have a second IP for my pi as seen in `ip addr show`

and as far as i can make out i have successfully bound lighttpd to the new IP:

```auto
pi@raspberrypi:/etc/lighttpd $ sudo netstat -nltup | grep 'Proto\|lighttpd\|dnsmasq\|dhcpcd'
Proto Recv-Q Send-Q Local Address Foreign Address State PID/Program name
tcp 0 0 192.168.0.32:80 0.0.0.0:* LISTEN 10944/lighttpd

tcp6 0 0 :::53 :::* LISTEN 2922/dnsmasq

udp6 0 0 :::546 :::* 698/dhcpcd
udp6 0 0 :::53 :::* 2922/dnsmasq

```

but

adverts are still showing unless i manually set the DNS?  
i also commented out the relevant part of `/etc/lighttpd/lighttpd.conf` for IPV6  
😕

EDIT

I actually get adverts even if i manually set the DNS

Your not suppose to bind lighttpd to the new IP address or you break the DNS to port 80 redirecting again.  
lighttpd should be running on the physical interface IP address eth0.  
And the Hue application should be configured to listen to the alias interface IP address.

Sh\*t

i better get undoing then!

i wanted pi-hole on the second IP as its less effort to change (i think)  
as i currently have everything running on the physical IP

any idea how id switch home assistant to run on second IP?

I dont have the software so have no clue.  
Try see what comes up if you do below:

`sudo grep 'host_ip\|listen_port' -R /etc`

no problem, ill ask that community

```auto

ok, so again, thanks to all that have helped me...but im still having some problems with pi-hole.  
😕

thanks to the above help settings are saved ok via the web interface.

however, if i do not set the DNS manually on my devices, i get resolve errors and cannot browse the web.

I also see adverts on android devices, irrespective of whether i set the DNS manually

I have disabled DHCP on my router and enabled in pi-hole.

Pi has been rebooted, as have the client devices.

If on a client, does below link work ?  
[http://pi.hole/admin/](http://pi.hole/admin/)

If not, the clients are not using Pi-Hole to resolve via DNS.  
Whats the IP address for Pi-Hole ?

Whats the output for below 2 on a Linux client:

`cat /etc/resolv.conf`  
`nslookup pi.hole`

Or if on a Windows client:

`ipconfig /all`  
`nslookup pi.hole`

ive omitted some data that i think may be sensitive?

on my laptop if i navigate to [http://pi.hole/admin/](http://pi.hole/admin/) i see the admin page...but only if i set the DNS manually

</div>

On the client it displays two different IP addresses while they should be one and the same (as Pi-Hole provides both DHCP and DNS now):

`DHCP Server . . . . . . . . . . . : 192.168.0.32`  
`DNS Servers . . . . . . . . . . . : 192.168.0.33`

Try running below one and reconfigure the network settings:

`pihole` -r

Ps. On the Windows client, you can run below 2 to renew the DHCP lease after you've run above command:  
\*Might need to run the Windows command line shell as user "Administrator"

`ipconfig /release`  
`ipconfig /renew`

And check again with:

`ipconfig /all`

</div>

ok i ran `pihole -r` and set up as 198.168.0.33 for pihole

i then ran the renew and release commands as admin on Win10 laptop, no good. no access to internet with a DNS resolve error...i have to manually set the DNS in adapter settings

output of `ipconfig /all` is:

```auto
   Default Gateway . . . . . . . . . : fe80::9221:6ff:fe7c:5079%7
                                       192.168.0.1

   DNS Servers . . . . . . . . . . . : 192.168.0.32
   NetBIOS over Tcpip. . . . . . . . : Enabled

```

why is it taking `192.168.0.32`?  
i have set a static IP for the laptop in Pi-hole admin?

fyi, when i set a secondary IP for the Pi, i chose 192.168.0.32 as `eth0:0`  
but added the bind rule for 192.168.0.33 into `lighttpd.conf`

EDIT  
the bind is missing due to re-install...i need to re-add again?
