Effective blocking of IP addresses with Safeguard

If you run a radio station, you want to make sure that only authorized users can access your content. Safeguard is a system that protects radio programs by restricting access to certain IP addresses and allowing you to block IP addresses. Here you will find answers to frequently asked questions about blocking IP addresses with Safeguard.

How can I block an IP address?

You can block IP addresses in Safeguard in various ways.

IPv4 address

To block a single IPv4 address, simply enter it in the input field.

IPv4 address and CIDR notations

If you want to block a group of IP addresses, you can use CIDR notations. Enter the IP address together with the corresponding CIDR prefix in the input field to block access from all addresses in this group.

IPv6 address

Safeguard also supports IPv6 addresses. Simply enter the address in the input field to block access from this address.

IPv6 address and CIDR notations

You can also use CIDR notations with IPv6 addresses. Enter the address together with the corresponding CIDR prefix in the input field to block access from all addresses in this group.

How can I allow an IP address again?

To allow an IP address in Safeguard, simply remove it from the input field. If you are not sure which IP address has been blocked, you can check the previously entered information. If you want to block an IP address again, simply re-enter it in the input field.

Can I block several IP addresses at the same time?

Yes, you can block several IP addresses at the same time by entering each address in a separate line in the input field.

Format for multiple IP addresses: IP address # Comment on the IP address

What does the comment in the input field mean?

The comment allows you to add a note to a blocked IP address. This can be helpful to remember later why you have blocked a particular address or address space.

How can I use Safeguard to protect my radio program?

To use Safeguard, simply enter the IP addresses that you do not want to be able to access your radio program. By blocking unauthorized IP addresses, you can ensure that only authorized users can access your radio program.

Here is a comprehensive example of IP address blocking

Note: The following example is only intended to illustrate how you can enter multiple IP addresses. Do not copy this example into the input field of your Safeguard mask. These are local IP addresses that cannot be blocked.

Example of blocking IP addresses

# IPv4-Adressen
127.0.0.1 # Localhost
127.0.0.2 # Test-IP
127.0.0.6 # Beispiel für gesperrte IP-Adresse
127.0.0.7/32 # CIDR-Notation für eine einzelne IP-Adresse
127.0.0.9 # Zusätzliche gesperrte IP-Adresse

# IPv6-Adressen
0:0:0:0:0:0:0:1 # IPv6 Localhost
0:0:0:0:0:0:0:1/128 # IPv6 CIDR-Notation für eine einzelne Adresse
::1/128 # Kurzform für IPv6 Localhost

In this example, various IP addresses have been specified with corresponding comments. Please note that these are local IP addresses and are for illustrative purposes only. Please enter the actual IP addresses that you wish to block.

By blocking these IP addresses in the Safeguard system, you can ensure that only the specified devices can access your radio program.

Safeguard offers you an effective method of controlling access to your radio program and preventing unauthorized access. By blocking the relevant IP addresses and allowing authorized addresses, you can ensure the security of your content.
