You can reserve and manage IP addresses with the IP Manager feature. You can reserve, manage and return IP addresses as blocks. IP addresses that are already in use are marked in color.
As a user, you can only reserve new IP addresses if the “Contract Holder” assigns you "Reserve IPs" permissions.
Reserve IP Addresses
In the "Number of IPs" field you choose the amount of IP addresses you want to reserve. An IP address can be used only one time, but different IP addresses from a block can be used in different networks, as long as these networks are provisioned in the same region where the IP block is located.
In the "Region" field you define which data center provides the IP addresses. An IP address can only be used in the currently selected data center. So you must reserve two separate IP Addresses for the two virtual data center locations in different regions (one in each data center region).
Returning an IP Address
IP addresses can only be returned in the block they were reserved in. Choose your IP Address block and then click "Block Release" in the lower right area.
You can allocate IP blocks to one or more groups and appoint permissions in the “Security” tab. No individual IPs can be distributed to different groups from one block. If you want this type of allocation structure, it is recommended that you reserve smaller IP blocks in advance and strategically allocate them to groups.
Using the "Edit" option you allow group members to perform management tasks on the IP block and delete as appropriate. The "Share" option allows a user to share the IP block with other groups as long as this user is also a member of the other group. In turn, the user can only pass on the permissions for other groups that they themselves originally received. For example, if the user can only share the IP block, then the user will only be able to assign permission to "Share" to the other group - but not the "Edit" permission.
Assign IP Addresses to a Server
You can only allocate a reserved IP address to a server if the corresponding network interface is connected to the Internet. It is not necessary to carry out provisioning beforehand.
You can also allocate further IP addresses to a network interface and use virtual IP addresses.
Please note that as users, you can only allocate IP addresses to a server if both the reserved IP as well as the Virtual Data Center has been assigned to the group of which you are a member. You must also have "Edit" permissions for the Virtual Data Center in order to make modifications. For more information, see “User Management”.
Manually Assign IP Addresses
There's the possibility that during certain Linux distribution installations that don't support /32 subnet masking a DHCP configuration could fail. You'll then need to assign the corresponding IP address manually, with the help of the Remote Console.
In this example, the assigned IP address is 220.127.116.11 and subnet mask is 'eth0' / 24 (or 255.255.255.0) in the network interface. The IP address of the gateway (in this case 18.104.22.168) is also required for internet access.
|ifconfig eth0 22.214.171.124 netmask 255.255.255.0|
|route add default gw 126.96.36.199|
The static IP can also be added with the configuration file. The "interface" file in the folder "/ etc/networking /" will need to be edited.
|# This file describes the network interfaces available on your system|
|# and how to activate them. For more information, see interfaces(5).|
|# The loopback network interface|
|iface lo inet loopback|
|# The primary network interface|
|iface eth0 inet static|
The modified interfaces should now be restarted.
ProfitBricks offers its own DNS resolver for each region.
DNS1: 188.8.131.52, DNS2: 184.108.40.206
DNS1: 220.127.116.11, DNS2: 18.104.22.168
DNS1: 22.214.171.124, DNS2: 126.96.36.199
We recommend that you specify an additional DNS resolver so your system's redundancy is assured.
