Block List

The Block List holds the IP addresses and user IDs that are restricted from accessing your video assets. One entry is enforced everywhere at once — Cloud DRM, Concurrent Access Protection, and the CDN all refuse it.

caution

Blocking takes effect for new requests within seconds. Check the evidence before you block a shared or carrier-grade IP address, because everyone behind it is blocked too.

Understanding the Block List​

The page has two tabs, one for each kind of entry:

  • IP Address: Addresses and ranges that are refused, whoever is behind them.
  • User ID: User IDs that are refused, wherever they connect from.

Each tab has its own list with the following columns:

  • IP address or User ID: The blocked value.
  • Date added: When the entry was created.
  • Note: Your own description of why the entry is there.
  • Actions: Controls for removing the entry.

To find an entry, type any part of its value in the Search... field above the list.

Managing the Block List​

Blocking an IP address​

  1. Open the IP Address tab.
  2. Select the address type from the Type drop-down list.
  3. Enter the address in the Address field. A range blocks every address inside it.
  4. Enter a Note describing why you're blocking it, so the next person to read the list knows whether the entry can go.
  5. Click + Add to block list.

An address that is already on the list can't be added a second time.

Blocking a user ID​

  1. Open the User ID tab.
  2. Enter the value in the User ID field. Use the user ID exactly as your backend puts it in the token — it's matched literally.
  3. Enter a Note.
  4. Click + Add to block list.

Removing entries​

Removing an entry restores access for that address or user across all modules.

  1. Select the checkbox next to each entry you want to remove.
  2. Click Delete. The counter above the list shows how many entries you selected.

You can also remove a single entry from the Actions column in its row.

What blocking does in each module​

ModuleEffect
Cloud DRMLicense requests from a blocked IP address, or carrying a blocked user ID, are denied with error drm_3030. The denied attempt is still recorded in the Request Log.
Concurrent Access ProtectionNew sessions are refused. A running session of a blocked user is stopped the next time the player pings, so playback ends without waiting for the session to expire.
CDNRequests from a blocked IP address, or carrying a blocked user ID, are rejected at the edge.

Entries added from Watermarking​

The Block List is shared with the Watermarking module. Blocking a user in Watermarking > Sessions also adds that user ID here, so the block reaches DRM, Concurrent Access Protection, and the CDN as well. For instructions, see Sessions.

Limits​

A tenant can hold up to 100 Block List entries in total, across both tabs. When the list is full, adding another entry fails until you remove one.
