Proxmox Server 1 Network Device 5 IPs

[Samoyed]

Hello guys i tried to bring up my networking, but i got some errors.
Hopefully u can help me out.

interfaces:

auto lo
iface lo inet loopback

auto eth0
iface eth0 inet static
address 111.111.111.112
netmask 19
gateway 111.111.111.111
post-up echo 1 > /proc/sys/net/ipv4/ip_forward
post-up echo 1 > /proc/sys/net/ipv4/conf/eth0/proxy_arp
iface eth1 inet manual

iface eth2 inet manual

iface eth3 inet manual

auto vmbr0
iface vmbr0 inet static
address 222.222.222.222
netmask 20
bridge-ports none
bridge-stp off
bridge-fd 0


My problem is that proxmox try to use all ips from the 20 subnet and not only 222.222.222.222 ip
can you explain my why proxmox try to use all ips from the 20 subnet ?
And what should i do instead ?

What you should do depends on what you're trying to achieve.
Netmask 19 and 20 are somewhat unusual. What was the intention behind that?
And what do you mean by "try to use all IPs from the subnet"?

These netmask came from the hoster and i want to achieve that i can assign an ip for each vm.
The vmbr0 assign all ips from the 20 subnet all 4096 ips and and the provider was down by the vmbr0.

A bridge does not assign addresses, but someone probably runs a dhcp server on the network.
