Opening SMTP Ports¶

For security reasons, outgoing TCP ports (25,24,2525, 387, 465, and 587) and UDP port (5060) are blocked by default on all VPS servers. This is to prevent the sending of spam. To remove the block, follow the steps below:

1. Spell out the domain zone. The A record of the domain must necessarily refer to the IP address of your server in HOSTKEY.

2. Send a request to technical support specifying the purpose for which you need to open outgoing SMTP ports and the address of the domain from which (or a subdomain of) it is being using.

   Attention

   We reserve the right to ask you additional questions about the domain name and your options for using it.

3. After analyzing the domain name, we will make a decision about opening ports for SMTP operation and inform you.

Are any other network ports blocked?¶

To protect client equipment from unauthorised use by third parties, we block all incoming traffic to the following ports:

How can I set up PTR records?¶

Login to the service control panel.

Go to the control panel for a specific server - tab Network - and click on the (Tools) (IP settings and DNS RTP management) icon.

Which DNS can I use for my server?¶

ou can use public cashing DNS-servers, for example, Google public DNS servers (IPs 8.8.8.8 and 8.8.4.4).

What happens when the traffic limit is exceeded?¶

For detailed information about traffic limits, overage costs, and fair use policy, please see the page: Traffic Cost.

If you have any questions, please contact us.

Is it possible to request an additional static ip address?¶

Additional addresses can be ordered by sending an email to [email protected] or by creating a ticket in your account. Prices for single addresses and blocks are indicated on our website.

Why doesn't my server's IP match its location?¶

Free location services often contain outdated or wrong data. Checking IP should be done using the RIPE service, which serves the allocation of addresses in Europe. The search form is on the first page of the service. You can always check the location of the server using the traceroute command.

Why my Internet speed is lower than it should be?¶

Lower Internet speed can occur for several reasons outside HOSTKEY's area of responsibility, for example:

• Hardware or software issues — check the condition of the network equipment, make sure the correct drivers are used and verify that the software used does not affect network availability (possible malware/viruses or the use of software that is not mandatory but is “eating up” network resources).
• The physical distance to the server and the status of network related operators — the further you are from the server, the weaker the signal strength may be. The access speed is judged in relation to HOSTKEY’s network. Issues with the connectivity to the networks of other providers (of higher level or local operators) can also lead to poor connection, meaning if you rent a server with 1 Gbps channel but test the speed from an overloaded network or from a network with a capacity of 100 Mbps, from a technical point of view, the HOSTKEY staff won’t be able to solve the problem.
• Traffic shaping — please, check whether or not you have received a system notification from us regarding exceeding prepaid traffic. In this case there was an automatic traffic shaping and you would have been informed.
• etc.

In order to identify possible problems on HOSTKEY’s side and to research optimal solution, please, provide connectivity test results from ping and traceroute commands. You can do it here.

After the completion of the tests, please, email the screenshots to our Support for examination. Use the email address registered in your client information with HOSTKEY.

Can I test the network speed and access to resources hosted with you without ordering a server?¶

To check the speed of accessing resources on our servers, you can use Speed Test or Looking Glass without waiting for the deployment of a test server.

Where to Check Firewall Settings and Network Security Rules in the Server Control Panel of InvAPI?¶

The server control panel of InvAPI does not have firewall settings or network security rules. You can check these settings by connecting to your operating system and using its internal tools, depending on the OS.

Is it Possible to Change or Add an IP Address in the Server Control Panel of InvAPI?¶

No, you cannot change/add an IP address for a server that has already been deployed (delivered) in the server control panel of InvAPI.

Is Torrent or other high-load traffic allowed for you?¶

HOSTKEY clients are prohibited from generating excessive amounts of multicast packets without coordination, overloading the access Ethernet port by more than 70% for more than 3 consecutive hours, and 100% usage (a "shelf" on the load graph) is permissible only for no more than 1 hour per day. Additionally, it is forbidden to generate an IP traffic stream of more than 20,000 packets per second without coordination with HOSTKEY on servers and more than 5,000 packets per second on virtual machines.
