Hi Fernando,
If it is to any type of event than I see no further justification, specially for commercial ones that can pay for a commercial offer that can supply the requires addresses in temporary basis.
This policy proposal has restrictions (and actually states in the proposal text) that resources can't be assigned for commercial use under 5.8.5 in the proposed policy solution: "The applicant must not use the assignment for any purpose which is commercial in nature". It then lists what is considered commercial, and what is not. This was added in after the Secretariat released their Impact Assessment. I believe that if an entity has a need for resources to be used in a commercial application, then yes, they should be able to source them through other means.
Normally the more costly part is the supplied broadband not really the amount of IPs that will be used for that occasion.
Yes, the connectivity would be the component that would cost more than the resources themselves, however it doesn't mean that we can't provide a way for resources to be provided for temporary non-profit use. Some events, training sessions, special interest groups, etc. don't have the capacity to pay for a temporary internet service hence where in-kind sponsorships and donations come into play.
Well, APRICOT have their own block already but anyone else that have such requirement and don't have their own blocks may just change their requirements. I see not much technical reasons to require a /20 of Public v4 for an event regardless how large it it is if you can well use CGNAT + IPv6 or 464XLAT. Why must every user has to have an unique public IPv4 address?
Could you please clarify what you mean by "anyone else that have such requirement and don't have their own blocks may just change their requirements"? The comment about using CGNAT and/or 464XLAT disregards my previous remark that "In many cases, CGNAT or 464XLAT isn't viable for larger conferences" and the reasons why. The APRICOT Secretariat has one really good line on their network operations page I'd like to point out - "Most importantly, APRICOT runs an open and high speed network recognising that delegates need to carry on with their day job reliably and without impediment while they are attending APRICOT". By providing delegates with dedicated public IP addresses this significantly (if not completely) assists them with being able to carry on their day job without any potential issues preventing access to their networks back home. The same can be said for other conferences and training sessions, meetings, and the like.
If there is anyone from the APNIC or APRICOT Secretariats reading that may be able to shed some light, are statistics kept on the number of IPv4 and IPv6 addresses that are assigned to end-user devices throughout a conference period? If so, is it possible to share these stats?
Yes there is the burden of keeping CGNAT source ports logs, but well, that's a natural cause of IPv4 exhaustion, and as IPv6 content support advances less CGNAT logs have to be kept. In resume this condition affects all equally in general.
I don't understand the relevance of this to the proposal.
Those who provide support for their networks back home may just use a Remote VPN connection which normally doesn't really matter what is the source IP address and if Public of under a CGNAT.
It's not as simple as just spinning up a VPN server. Implementation of VPN servers requires significant planning. Not all participants may have VPN capabilities (or the ability to implement VPN access). If people have VPN access while away then that's great and could be used however, people that don't need to be catered for. It's not for us to tell them how they must operate or access their networks.
Also they can have IPv6 on their destination/infrastructure and if necessary whitelist only the address in use at the point in time.
Similar as my last reply, not all networks may have IPv6 connectivity for whatever reason (which I won't go into discussion about here so as to not go off-topic). While it's a good thing if they do, people who don't need to be supported. On a side note to this, APRICOT does run a IPv6-only SSID which has a complete absence IPv4 on the network.
