I downloaded the encap.txt file just now and it doesn't match the gateway list. Is it not being updated or has something gone wrong in the process? 73, Don

For places where it is just a leftover of the packet radio days, I agree. Today I deleted a number of old BBS records, and a few hours later I got a mail back that one that was still in use. We cannot do that for all 3000 active records. Rob

> No, expectation is that people getting AMPR address space should > have the subnet they're in registered with the portal. That includes > non-connected hosts and /32s. Is it really a good idea to base the cleanup on data in the portal? I mean, the guy running the portal clearly does not have the resources (or the motivation?) to do even minor maintenance on it, let alone finish work on features like the DNS registration that have been in incompleted state for years. Is it a good idea to make our entire network dependent on that? I cannot remove a subnet that was erroneously added in the past (and where user subnets where added inside) without deleting those, and a request to the maintainer to do that outside the portal UI that I sent months ago is still not processed. I also cannot add any regional subnets for which parts are already registered to users. The whole implementation of subnet hierarchy and record ownership is much too strict, it only works when everything is done "the correct way" on the first try, which simply is not realistic. Compare it to HamnetDB where you can simply reshuffle the whole subnetting by inserting, deleting or editing existing records within the existing hierarchy. I also don't like the idea to send a request to all users to "register themselves" and then being bombarded with allocation request mails from the portal that all need to be manually edited because the requesting user cannot specify an existing allocation to be registered. Users that do not understand the whole mechanism cannot be ignored, because either you don't process the request and it remains on the todo list, or you reject the request and those users just click the links in the rejection mail which results in the same request being posted again :-( In 44.137.0.0/16, really only the users that want to run an IPIP tunnel are registered in the portal, there are many other users that connect in a different way. Luckily we are not affected by this cleanup because we are BGP routed, but at the same time that also shows how this method is failing. After all, what does the routing method have to do with the DNS contents? Basically nothing. Why should all our inactive records remain there while those of other countries are deleted even when they may be active? When we want to clean the DNS, we should look at the situation on a country by country base. I am all for deleting entries for callsigns that have expired, and in fact I regularly do that. Probably other countries also have lists of active callsigns and a quick scan can be made to delete all expired callsigns and probably also those records that are not related to callsigns. We could request all coordinators to send a list of active callsigns, and we could process those lists to generate a deletion list like I already do for my area. We could also ask each coordinator what is the state of IP packet or other use of those addresses in their country, and maybe get whole networks deleted when they no longer exist. I will try to dig in the old data I still have saved (for my area) to generate a list of callsigns and the date of last registration or reconfirmation, and try again to contact all callsigns with records before a certain date and delete them when there is no reply. This should clean out more records than the previous run, where I only deleted those registrations where the owner replied they no longer required them. Rob

Hi group, hello Thomas, IIRC the initial assignment was in fact given to me by you and Paul, so I'm happy to hear from you again. :) On 02/07/16 23:55, Thomas Osterried wrote: > Hello, > > well, a longer tradition than the quite new portal are the country-wide IP-Koordinators. > > In DL, we have the coordination team of three people (dd9qp, dg8ngn, dl9sau) and we delegate the responsibility of the local assignments to the regional coordinators. This concept goes back to the last century. > From the regional coordinator, Wolfgang had got the initial assignment of his IP addresses. That is correct. And that was kind of "status quo" when I had to quit Packet Radio activity. But the first thing I found when I searched for infos on the current state of IP in PR was that my IP's no longer do exist (which in fact is not really the problem for me, as I really was not active for a long time. So, no complaints on that from me, that's perfectly OK if there's some need for IPs. > Some time ago, we did a clean-up of the old 44.130 packet-radio block in communication with the regional coordinators. > > What's with the portal? - I think we need discuss that. It had been no relevance for us (since no one requested it), and I'm not sure, how it fits in a concept of the country coordinator system (unless a country coordinator defines a do-what-you-want-netblock for self-allocation - but how this may be integrated in a working routing concept??). I think the portal would not work that good with a concept like the formerly used one with using the IP for granular routing over PR network. But I seem to remember discussions that the "routing feature" would not be needed any more and the whole german IP PR network should be seen as one big block (which I do not really support from my standpoint as sysadmin). > Region ofr.de (44.130.62.0/24) was resigned 2013-07-31.

Nine years after the last update. forward- and reverse- entries were inconsistent: the reverse file had the serial number 2002062201 (I assume 2 years before). > > I do not like to blame anyone, but it may be useful in that discussion. 9 (or 11) years after the last coordination of the subnet and 2.5 years after your regional coordinator stated that all records could be removed, you recognize that dg7nef, dg7nef-2 and dg7nef-gate ( 44.130.62.20, .18, .19) have been passed back. And that lead to my problem with portal.ampr.org as I still had my own local acting DNS serving as "Master" for the zone on requests from my network, so I could at least keep the IP adresses I did contact in a state that did work for me. Yes, split DNS and multiple masters are an ugly thing. But it did work locally then. > This emphasizes both, the difficulties we'll get, even years after a clean-up, and on the other site the need to have a clean-up (the /24 had 57 entries (22%) and we finally got one complain (Wolfgang had 3 addresses -> 5 %).

Well, in fact no complains from me so far, just a bit confusion on my side. ;) > And imho, it also shows the country- / regional-wide coordination concept makes sense. Currently, we've 35866 IN A records in ampr.org. Imagine we'll have 10 requests a day on the list of the pool of every user, we all will have to read the next 10 years about every individual issue.

Dumb question - 44.130 IP address?
by Dg7nef 07 Feb '16

07 Feb '16

One kind question, first of all, after a forced break due to changing my home address and various other reasons not to be discussed here I had to learn my IP adresses assigned to me long ago and that I used for a long time ago are no longer existing. OK, maybe I can understand the reason for that. Now I'm searching for that "portal" to register myself for getting a new IP assignment for being able to start playing with Amateur Radio Packet applications and so on, so I search for the portal. Well, there is a portal. But that portal is not showing up at all when you try to contact it. Does that mean you have to have an IP to register for an AmPR IP, but no wait - I just want to register for it? Can you please enlighten me what is going on here? I just don't understand it right now. Thanks, Wolfgang

> What would you have me do? It's clear that the majority of the entries in > the DNS are bogus. We have NOTHING to reference except the portal data. > Doesn't it make sense to try to get that data in order? Yes, but as I mentioned many times before, there is no sane way of migrating the data that *is* still valid towards the portal. There is no clear way for the user to request their existing allocation to be loaded into the portal. Not automatically (e.g. by querying the DNS), not manually (by filling in a form with existing addresses). One can only ask for new allocations and place a comment that says in fact one wants to move an existing allocation. I cannot ask the users to do that, and I don't like to edit all those requests manually. I think the portal should facilitate migration of existing data at least until that process is completed. There should also be procedures to migrate large blocks of data, as our own network infrastructure has hundreds of hosts that I do not want to enter in a webform one by one! I have recovered all update mail messages sent to the portal after 1994-01-01 and have added a date stamp to all the lines in my own hosts file with the latest date of an addition of data for each callsign. The file is available at http://pe1chl.nl.eu.org/hosts/hosts.137 Today I have done another mailing and a local amateur radio newssite has placed it on their newspage. This time I requested all the users that want to *keep* their allocation to reply by mail. When I get a reply or make a new registration I update the stamp to the current date. Next month I will just delete all records with a date before 2010. That should get rid of all the records from "the old days" and only leave those that were added during our more recent experiments. Last time I did this (two years ago) I kept the records for those that I could not reach, but this time those will get deleted. (of course they can always request to get them back when they notice it) Rob

If other AMPR coordinators have similar approaches, then DNS entries mean everything to the IP allocation be it a subnet or a /32. > > --David > KI6ZHD This is not how I handle allocations... in the area I manage one can allocate individual addresses or subnets, and when they are subnets the address range of the subnet is reserved but not each address in the subnet needs to have a name attached. However, all traffic for addresses without associated name in .ampr.org is filtered at our internet gateway. So when you want to actually *use* an address outside the local radio network, it has to have a name. (this is the same policy as in the gateway at UCSD) Rob

However, it was not processed. This makes me pessimistic about the maintenance resources at the portal, and reluctant to spend a lot of time filling it with information that apparently can never be modified. Rob

Annoying, but it should take only a few minutes, > less time and more productive than arguing about it on the mailing list. It is the 44.137.24.0/22 subnet as I mentioned before. But be careful: those children are IPIP gateways and have that subnet registered in their gateway system. I'm sure when you delete them through the UI, the subnet will be deleted from their gateway as well. That is not good. I wonder what the database structure is and if you could maybe just delete the record from the database without affecting the children. When there are all kinds of pointers back and forth between parent and child records, that would be something that needs to be fixed. It should be easy to add and delete subnet levels between existing ones, e.g. a new regional subnet between a country subnet and users. We are re-arranging things all the time as the network develops. Probably the subnets should just be stored neutrally, and the parent/child relationship should only be established at the time the records are retrieved for display. And deleting a subnet should not infer deleting everything that is in it, the contents should just be promoted to the next higher level. Rob
