I have server in OVH. I buy 13 IP blocks, added to server but ip not working.

My step: I added new IP block to my /etc/systemd/network/50-default.network, i added this line


In DirectAdmin i added ip from this block:

beacuse my block have 4 IP. I set netmask to, assign IP from block to domain tr-bahis.com and restart server. Domain still not working. In domain provider i set record A to, 2 weeks ago.

When I ping an IP outside the server, then I get no response, while when I ping while logged in, I get a reply after a while.

I used this tutorial https://docs.ovh.com/gb/en/dedicated/network-ipaliasing/#debian-9-ubuntu-1704-fedora-26-and-arch-linux_1 beacuse i have Debian 9 on my server. I contacted OVH support on this issue and they said that it should work and that their help ended.

My /etc/systemd/network/50-default.network:

# This file sets the IP configuration of the primary (public) network device.
# You can also see this as "OSI Layer 3" config.
# It was created by the OVH installer, please be careful with modifications.
# Documentation: man systemd.network or https://www.freedesktop.org/software/systemd/man/systemd.network.html


Description=network interface on public network, with default route

I tried to find out in several places what I should do to make it work, but unfortunately the only answer was to completely reinstall the system for something other than debian 9, but for me it's no solution.

Does anyone have a better idea why it doesn't work? :(

  • @A.B Hello i added command result to my post :) When i set /32 or /30 in network file still not working. I don't know what is wrong, and why ip block not working. From ovh i get ip block with /30

  • Well I don't know how to help you further. Maybe you should try with /32 rather than /30 and use .165 to test rather than .164 (test with only one IP until it works). Good luck.
