- 2001:db8:abcd:30::/60
- 2001:db8:abcd:34::/62
- 2001:db8:abcd:20::/62
- 2001:db8:abcd:36::/63
- 2001:db8:abcd:60::/64
| Answers Explanation & Hints:
The prefix matching logic works the same for IPv6 networks as for IPv4 networks. The fourth hexadecimal group of the match specification is 0x0030, which is 00000000 00110000 in binary. To match /60 prefix length, the fourth hexadecimal group of a network must be between 00000000 00110000 and 00000000 00111111, that is, between 0x0030 and 0x003F. The prefix length must be between /61 and /63. |
