What is the most compressed representation of the IPv6 address 2001:0db8:0000:abcd:0000:0000:0000:0001?
- 2001:db8::abcd:0:1
- 2001:0db8:0000:abcd::1
- 2001:0db8:abcd::0001
- 2001:db8:0:abcd::1
- 2001:0db8:abcd::1
| Explanation & Hint:
The IPv6 address 2001:0db8:0000:abcd:0000:0000:0000:0001 in its most compressed format would be 2001:db8:0:abcd::1. The one leading zero in the second hextet can be removed. The first hextet of zeros would be compressed to a single zero. The three consecutive hextets of zeros can be compressed to a double colon ::. The three leading zeros in the last hextet can be removed. The double colon :: can only be used once in an address. |
