IPv6 Flashcards
IPv6Rd is stateful
False
NAT 64 stateless does not assist in maintaining IPv4
True
NAT64 stateful maps 1:1 and maintains end-to-end communication
False, it maps Nv:1v4, false there is no end-to-end communication maintenance
NAT64 implies the use of DNS
True
In 6in4 DNS64 translates an A record into an AAAA record so that an IPv4-only host can access an IPv6-only network
False, DNS64 applies to NAT64, its operation is correct but the goal is to provide access from v6-only clients to v4-only servers
NAT64 uses the 2002::/16 prefix
False, 6to4 uses this range
6in4 encapsulates IPv6 over IPv4 and uses protocol number 41
True
6to4 is indicated for v6 clients to access v4 networks
False, it is a router-to-router protocol. The address is formed by the global address prefix 2002:wwxx:yyzz::/48, where wwxx:yyzz is the host’s public IPv4 address converted to hexadecimal
6to4 has the IPv4 relay/remote router address embedded in the IPv6 address
True
The /64 prefix is used by NAT64
False, a /96 + 32 (IPv4)
In nat64, the core and access of the operator can be IPv4 only
False, they must be IPv6 only and the cgnat must occur at the edge
___ - translation - Embeds only part of the remote IPv4 peer within IPv6 ___ - Tunneling - Tunnels IPv6 over IPv4, protocol 41, should not be used with isis
6rd, 6in4
___ - translation - Embeds the entire remote IPv4 peer within IPv6
6to4
What is the size in Bytes of the GRE overhead?
24 bytes
Which tunneling technique is used by the command Tunnel mode IPv6ip
6in4
