The network designer needs to use GLOP IP addresses to make them unique within their...

C: GLOP addressing is defined in RFC 2770, assigning a portion of the 233.0.0.0/8 range for each AS based on their 16-bit ASN. This allows each AS to use a /24 of globally unique multicast addresses without coordination from IANA.

Other options:

A: 239.0.0.0/8 is the administratively scoped multicast address space.

B: 224.0.0.0/24 is reserved for local link-scoped protocols (e.g., OSPF, RIP).

D: 232.0.0.0/8 is the Source-Specific Multicast (SSM) range.
