ICMP and IPv6
See how ping and traceroute use ICMP and the TTL, and what IPv6 changes about addresses and headers. About 13 minutes.
Which IPv6 address is a valid short form of 2001:0db8:0000:0000:0000:0000:0000:0001?
- A2001:db8::1
- B2001:db8::0:1::
- C2001:db8:1
Show the answer
2001:db8::1. Leading zeros are dropped, and the run of five zero groups becomes ::.
