You own a home network connecting through an always-on connection and need to assign IPv6 addresses to your routers because you want to follow the guidelines spelled out in RFC 3177. you want to design your network with the correct prefixes.
Which prefix would your ISP likely allocate to your network?
A.
47-bit prefix
B.
48-bit prefix
C.
64-bit prefix
D.
128-bit prefix
I was looking over the answer for this question, I found that the answer B should be correct according to the following paragraph extracted from RFC 3177:
– Home network subscribers, connecting through on-demand or
always-on connections should receive a /48.
– Small and large enterprises should receive a /48.
– Very large subscribers could receive a /47 or slightly shorter
prefix, or multiple /48’s.

In March of 2011 the RFC 6177 was published.
This document obsoletes the RFC 3177 recommendations on the assignment of IPv6 address space to end sites.
RFC 3177 recommends to use /56 and /64.
In that case C will be an answer.
Yes philipp you are right but the question says for rfc 3177
B is the answer
http://www.ietf.org/rfc/rfc3177.txt
In particular, we recommend:
– Home network subscribers, connecting through on-demand or
always-on connections should receive a /48.
– Small and large enterprises should receive a /48.
– Very large subscribers could receive a /47 or slightly shorter
prefix, or multiple /48’s.
