Resizing an IPv4 network - BlueCat Integrity - 9.5.0

Address Manager Administration Guide

Product name
BlueCat Integrity

With an IPv4 block created in Address Manager, you can resize an IPv4 network.

Note: In order to support two allocatable IP addresses, /31 networks are special cases that do not have network, gateway, or broadcast addresses. Resizing or splitting larger networks to /31 will remove associated network, gateway, and broadcast addresses.
Note: Resize and merge operations cannot be performed on a /31 network if a DHCP range is present on the network.
Note: Resizing networks to and from /32 is not supported.
To resize an IPv4 network:
  1. Select the IP Space tab. Tabs remember the page you last worked on, so select the tab again to ensure you're on the Configuration information page.
  2. From the configuration drop-down menu, select a configuration.
  3. Under IPv4 Blocks, select the network that you want to resize.
  4. Click the menu beside the network name and select Resize.
  5. Select a resize option and specify the resize values in these fields:
    • CIDR block—select this option to specify the network size using CIDR notation. Type the address and size in the CIDR Block field.
    • Range—select this option to specify the network size as a range of IP addresses. Type the starting and ending addresses in the From and To fields.
    • Address—select this option to specify the network size with an IP address and netmask. Type the IP address and netmask in the Address and Netmask fields.
  6. Click Yes.
