RE: New Version Notification for draft-koodli-ipv6-in-mobile-networks-02

Hi Teemu,

thanks for the input.

Agree to your point about adding IPv6 features and not IPv4.
However, the description of DHCP-based addressing is for LTE, not 3G.
And the description is about having DHCP as a mechanism to manage the available IPv4 addressing pool.
Are you saying that it should not be available or should not be used?

Regards,

-Rajeev

Hi Rajeev, all,

I'm worried about the on-demand DHCP based address allocation descriptions herein. 

Majority of 3GPP devices do not implement DHCP at all today for 3GPP access, because it is optional and gives very little when compared to mandatory PPP-like address allocation during bearer establishment procedures. 

Introduction of DHCP for significant host population (to get statistical savings) just for the deferred IPv4 address allocation feature does not sound right thing to do for me.

We should be adding IPv6 features to hosts, not IPv4 features.

Best regards,

Teemu
