IP Addresses
The Cisco database stores IPv4 and IPv6 addresses in the same fields in a BINARY format. To get IPv6
addresses, convert to hex notation, for example:
addresses, convert to hex notation, for example:
20010db8000000000000000000004321
. The database
follows the RFC for storing IPv4 addresses by filling in bits 80-95 with 1’s, which yields an invalid IPv6
address. For example, the IPv4 address 10.5.15.1 would be stored as
address. For example, the IPv4 address 10.5.15.1 would be stored as
00000000000000000000FFFF0A050F01
