What is HA-IP?

HA-IP is a ‘highly-available’ IPv4- and IPv6 address that allows you to forward TCP-traffic to a single BladeVPS. As this IP-address is located ‘outside’ of your VPS(es), you can always refer this address to any VPS of choice.

When, for instance, your VPS has to go down because of temporary maintenance or to restore a back-up, you can make a clone of your VPS which enables you to set your HA-IP to your new VPS. This allows you to perform any actions on your original VPS, without having any impact to the users of that server.

Can I let my HA-IP execute a failover automatically?
It is not possible to set an ‘automated’ failover through your control panel with HA-IP basic but you can do so with HA-IP pro, see this article. Through our API, it is possible to configure an automated failover for HA-IP basic as well. It does however require quite some active monitoring (like our TCP-monitoring) and programming skills to make use of our API. You can consult the API documentation for some examples of solutions.
 

Can I adjust the name of my HA-IP?
Change the name of your HA-IP
Yes, you can adjust the name of your HA-IP, just like your VPS or private network. In order to do so, go to your control panel, select your HA-IP under 'BladeVPS'. Then, click the cogwheel (Advanced Settings) in the upper-right corner and select 'Change Name'.

What are the default TransIP settings / what kind of traffic does the HA-IP send through?
With the default "TransIP settings", only traffic destined for port 80 and 443 will pass through HA-IP. All other traffic will be rejected by our firewall, unless you have set a specific port at ‘turn on advanced settings’. Please make sure not to let your traffic run to your HA-IP unless you have correctly set the port for this. You can not have your HA-IP forward any UDP traffic.

Does HA-IP pass on the 'remote IP'-address with http(s) and mail traffic?
At this time HA-IP does not yet pass on the external IP-headers. Your logfiles will show the IP addresses of the 'loadbalancers' HA-IP uses itself. This is for example not optimal for the tracking of visitors of your website and we are looking into the possibility to make this possible.


Change the PTR-record of your HA-IP You can change the reverse DNS in the control panel below the header 'Reverse DNS'. Select Change DNS in order to enable the option. After that you can set the desired reverse DNS.

Please note! A valid reverse DNS has to be a FQDN (Fully Qualified Domain Name)! An good example is 'server.domainname.com'. Not correct is for example 'haip-server'.

Can I choose or adjust the IP-address of my HA-IP?

 

  • At the moment, the allocation of IP-addresses is being performed automatically (just like this is the case for a BladeVPS). Therefore, it is currently not possible to choose or adjust a (HA-)IP address. The IP's which HA-IP can use are from specific ranges.
  • You can not transform an existing IP from an active or cancelled VPS to a 'HA-IP'. As stated above the IP's HA-IP uses are from specific ranges.
  • Your HA-IP will direct to the primary IP-address of the designated VPS. Linking to a different IP-address on a VPS is a feature which we are looking into to implement.
