2.1.5 CHANGING DNS SERVERS

If you wish to change a DNS server delegation, click on the desired block and then click on "AltDel."

The following screen will display the information of the DNS servers that are currently registered.

To change this, simply delete the name that is displayed on the screen and enter the name of the new DNS server.

Now the system will check that the new servers are already configured to answer for the block's inverse zone.

The process will only be concluded if the servers are configured.

2.1.6 REMOVING DNS SERVER DELEGATION

To remove a DNS server delegation, simply click on the desired block and then click on "RemDel."

The following screen will display the information of the DNS servers that are currently registered, together with the following warning:

"Attention: By clicking on ENTER you will remove the DNS delegations of the 200.0.16/24 block, as well as all allocations within this block. Click on ENTER to confirm the removal, or click on RESET to cancel."

To conclude the removal process the user must click on "Enter."

2.1.7 VISUALIZING THE UTILIZATION OF A BLOCK

The system allows a graphic visualization of the utilization of an IP address block allocated by LACNIC or reallocated to a client.

In order to visualize the utilization click on "Allocation Map," next to each block directly allocated by LACNIC.

Or click on "Map" if you wish to visualize the utilization of a block that is reallocated to another entity.

The system creates an image in real time of the information of the allocations and DNS delegations made within this block that are registered in the system.

[ FIG 21 - Map ]

This image uses a color code to indicate utilization:

  • White indicates free blocks;
  • Grey indicates allocated blocks;
  • Light green indicates blocks that have delegated DNS servers;
  • Dark grey indicates blocks that are allocated and have delegated DNS servers.

It is also possible to check the status of the utilization of an allocated block by clicking on "ShwAsig".

[ FIG 22 - ShwAsig]

 

[ FIG 23 - Utilization List]

The system displays all existing reallocations for each prefix and the name of the entity that received them. If a block has delegated DNS servers, it will be shown with the word "Delegated" before the block/prefix.
