What you mean by Unlimited monthly bandwith?

You can send/download as many data per month as your server can handle. There is no limit on data.


Why may I need more IP addresses?

More IP addresses is needed when it is secured pages on the server. It is necessary to have one IP for each SSL certificate. More IP addresses You can use in other cases of course, more similar services on one server with another configuration etc.


What does it mean "VLAN"?

Virtual Lacal Area Network (VLAN) is transparent connection of two or more Local Area Network (LAN) on the second level of the network layer.


What should I do if I need operating system for my server?

We are able to ensure installation and configuration of basic operating system (Debian, Ubuntu) within service Server Housing. Administration of the server we ensure within service Dedicated server, Managed Server and Virtual Server.


Will I really get a /96 IPv6 address segment with every server hosting service?

The IPv6 address segment is bound to the client, not the service. If you order any server housing program, you will receive your segment of IPv6 addresses. No additional IPv6 address segment will be provided if you order one or more additional housing programs.


Is the DNS reversing entry important for me?

Yes, DNS (Domain Name System) reverse entry is important. A DNS server contains PTR records which translate the IP addresses based at the domain name. This is very important (not only) for mail services. The domain name can include whatever word, but the most often contains the name of the domain referred to the IP.


How do I set up my reverse lookup?

In the case of virtual servers, the reverse DNS lookup may be set up directly in the control panel interface. As of now, this service has not been implemented in non-virtual services. As such, requests for setting the rDNS need to be sent via the control panel or via e-mail toThis email address is being protected from spambots. You need JavaScript enabled to view it..


What does ‘aggregating ratio’ mean?

The aggregating ratio states the maximum number of users to whom the connectivity is offered. Example: an offer of connection at a aggregating ratio of 1:24 means that the connectivity band will not be divided to more than 24 parts! For more information on the aggregating ratio, visit: www.coolhousing.net/en/aggregating-ratio.


What does "shared connectivity" mean?

The overall capacity of the line is divided among all customers currently connected. However, the current usage of the overall capacity amounts to ca. 20%.
For more information on shared connectivity, visit: www.coolhousing.net/en/aggregating-ratio.


What is the aggregating ratio at the Coolhousing DC?

The typical aggregating ratio in our data centre is 1:24. The only exceptions are dedicated lines that offer 1:1 aggregating ratio.


Is the data backup service included in price?

No, data backup service is an optional service. It is charged due the data amount. Backup is only a part of virtual server services.


When may I use the ordered service?

Virtual server services are activated within a maximum 10 min after processing the payment. Physical server service orders are generally processed during workdays (Monday to Friday) from 8:00 am to 4:00 pm.


I need to connect to my external data repository via Samba. How do I do it?

Access to a data repository using the Samba (smb) protocol is restricted to only the IP address of your server. Connection is possible using the following methods:

  1. From OS Linux/unix: smb://[backup_server_address]/[login]

  2. From OS Windows through the platform "Remote computer", or via "Start" -> "cmd" and enter the path: \\[backup_server_address]\[login]\

  3. From OS Windows with a terminal command: C:\Users\Administrator>net use h: [backup_server_address]\[login] /USER:[LOGIN] [PASSWORD]

I need to connect to my external data repository via NFS. How do I do it?

Access via NFS and volume mounting from your server can be carried out as follows: mount [backup_server_address]:/mnt/clients/[LOGIN] /folder_on_my_server/ Access to the data repository (volume) is restricted only to your server (limited by the IPv4 address).


What do connectivity slashes mean, and what, for example, does 100 Mbps/32 Mbps mean?

To achieve a better throughput in our datacentre, we split the connectivity to networks with direct peering, NIX, FENIX, and transit. The value in the connectivity name expresses both the maximum throughput on the switch’s dedicated port and the amount of connectivity of the direct peering dedicated to the connectivity tariff. Based on the tariff, the connectivity is also supplemented with a transit connectivity.

100 Mbps Basic Line
100 Mbps to NIX, FENIX
100 Mbps transit connection

1 Gbps Basic Line
1 Gbps to NIX, FENIX
1 Gbps transit connection

1 Gbps Advanced Line
1 Gbps to NIX, FENIX
1 Gbps transit connection

If the connectivity is labelled as a dedicated one, the service runs on a 1 Gbps dedicated port. The amount of the dedicated transit connectivity can vary but it is usually higher than 10 Mbps. The remaining port capacity is generally completed by direct peering connectivity.

If a slash is missing in the connectivity parameter, then the amount of NIX and transit connectivity is the same, except for dedicated links, which are automatically operated on a 1 Gbps dedicated port, and for dedicated transit connectivity NIX connectivity is figured into the remainder of the port.


What kind of technical support can I expect?

It is essential to differentiate between server administration and administration of its contents. Our technical department monitors the operation of all servers within the entire data centre, continuously 24/7, thanks to which in the event of an outage of any of the components in DC that limit or prevent the operation of our provided services, you can adequately intervene and renew service operation as soon as possible.


What can customer support help with?

It is best to contact our customer support staff via an "authorised request" in the client section, by e-mail or by phone and to contact them with all general questions, with notifications of service outages and with questions regarding orders, invoices and payment methods. Customer support can also start, stop or restart the server or restore it to its default settings upon authorised request. In cooperation with our technical department, the customer support team can also help you resolve individual requirements, for which, however, there will be a charge if an administrator has to intervene.

Customer support generally is not intended to provide support for services of third parties or cooperation in preparation of your applications or websites (coding, programming, analytical or other work).
