DNS A record - just gateway, or all hosts? - 44net

Every single 44net IP address needs an A record to be routed. Your coordinator needs to add this to the database. On 9/22/2023 1:34 PM, Tom M0LTE via 44net wrote:

Hi

If there is no DNS A record for a tunneled amprnet destination host,

the traffic is not forwarded in either direction. Does this mean a single A record for my gateway (44.61.31.1/27 <http://44.61.31.1/27>), or multiple A records, one for each IP of my subnet? Thanks Tom M0LTE

Outbound thru UCSD to the Internet will work without a DNS record

Out of interest does that include replies, i.e it's stateful? Cheers On Sat, Sep 23, 2023 at 11:25 PM Steve L via 44net <44net(a)mailman.ampr.org> wrote:

This is only the case for inbound traffic off the Internet thru UCSD. Outbound thru UCSD to the Internet will work without a DNS record as will traffic in both directions directly to other gateways. On Fri, Sep 22, 2023, 3:17 PM Charles Hargrove via 44net < 44net(a)mailman.ampr.org> wrote:

Better to have a standardized way for all than cause confusion for newbies. There is no harm in creating an A record for each IP. So what if it is unused. On 9/23/2023 6:24 PM, Steve L wrote:

There is a lot of background noise on the Internet. So if a /24 lan is pointed at a gateway, it makes sense to have a per host inbound traffic filter. The reserved /24 for the lan, may only have half the on air hosts for now, and the rest of the address space is for future growth. The other thing is most people do not (or not historically) have a symetric internet connection. On Sun, Sep 24, 2023, 3:41 AM Tom M0LTE <tom(a)m0lte.uk> wrote:

As a newbie, this bit of the process hasn’t been particularly transparent. I’ve got a wiki account and I’m not afraid to use it. But it could make sense for every IP to get an entry by default, eg: 44.61.31.1 -> 1-31-61.m0lte.ampr.org or something. Then things would work as expected, out of the box. And reverse dns could be used to quickly identify an owner. CNAMEs could be added if something more descriptive is desired. Just observations of an outsider.
