See my comments inline. ~ Vijay > 1) The FQDN option needs, I think, to look a lot like the FQDN option > for > dhcpv4. The option i defined here is, for just transfering the FQDN releated to temporary address. It is similar to hostname option in DHCPv4. I will rename it to hostname option. I feel like, since the DDNS updates are still TBD, we can define the FQDN option with appropriate fields needed later, once DDNS specs are finalised. > The name encoding must be specified. Yes. It is needed. I will add the appropriate text. > There needs to be > specification about hosts who do not initially know their entire fqdn. > There needs to be a way to communicate about which party (if any) will be > updating DNS. It's probably on my plate to produce that, actually. For the temporary addresses, DNS update is done by server. So, these fields are not necessary. > > 2) The subnet-selection option text should not compel the server to > somehow > obey the client's suggestion.

This is the only way the client can tell its prefernce for the prefix. If the server is not supposed to allocate address for that prefix, then it wont. If the client is not very particular about the prefix, it should not use this option. This option will be more helpful in the network with two prefixes and the client wants a particular one. > > A nit: isn't the option-len sufficient to determine the prefix length? > Is > the prefix-len byte necessary? No, it is not sufficient. Without the prefix-len field, you cannot find out the exact prefix length. For example, you can identify whether the prefix length is between 57 and 64. You cannot find out the exact prefix length. > > 3) The encoding for the domain names in the NIS and NIS+ Domain Name > options should be DNS encoding, shouldn't it?

Let me know, if there are any serious issues on this. _______________________________________________ dhcwg mailing list dhcwg@ietf.org https://www1.ietf.org/mailman/listinfo/dhcwg _______________________________________________ dhcwg mailing list dhcwg@ietf.org https://www1.ietf.org/mailman/listinfo/dhcwg
