  • 250, obviously todo with the 250th anniversary of july 4, 1776, but no content there yet.
    jtk@infosec.exchangeJ jtk@infosec.exchange

    @paul_ipv6 I count 16 out of 58 (~25%) EO names that have no corresponding WWW page or that return a 404. Names that land somewhere are often just redirects to a whitehouse.gov page or tend to be pretty light on content. A few are just some sort of login page. If you're a fan of small government I guess you would be OK with this?

    @jianmin My own view of all this might best be described as budding nostalgic, doomerism skeptic.

    Where there were sysadmins in the org, many are now little more than cloud vendor management admins. The skills needed are different and arguably require less techical wizardry than ever.

    It seems to me, AI is going to drive many devops and in-house developers to the same fate - centralization of the engineering into big backend orgs and their platforms. Someone(s) remains behind to manage tech deployment in the org, let's call it a tech janitor.

    A hollowing out of the old school geeks in every org continues, but on the bright side maybe never quite fully eliminated? Everyone becomes a little more geek in the process?

    @paul_ipv6 Working on finally finishing up a paper related to this, but suffice to say I think Quad9 is taking a very reasonable position here.

    There continues to be interesting DNSSEC-related outages, even "impactful" ones, but I think one could argue NTA getting it wrong is at least as risky as an outage. Hmm.. maybe something for future work . 🙂

  • #Hosting provider AlexHost (#AS200019) is raising the price of their low end U1 VPS (1 CPU, 1.5GB RAM, 10GB NVMe) from 4€/month to 6€/month.
    jtk@infosec.exchangeJ jtk@infosec.exchange

    @i There are probably quite a few better deals financially. The alexhost hardware (CPU) in this case is also quite old. The interesting part to me was just the matter of the increase (even on this old stuff), but I think really this was an excuse to weed out some abusers.

    #Hosting provider AlexHost (#AS200019) is raising the price of their low end U1 VPS (1 CPU, 1.5GB RAM, 10GB NVMe) from 4€/month to 6€/month. Two reasons for the increase are:

    "The price of RAM has increased."

    "[...] abuse of extremely cheap plans has also increased significantly."

  • IP4 prefixes for.ir TLD name servers are being announced.
    jtk@infosec.exchangeJ jtk@infosec.exchange

    IP4 prefixes for.ir TLD name servers are being announced. TCP/UDP over IP4 queries are getting responses from most of those name servers.

    There are inconsistencies between what is in the root and now in ir. The root zone has IP6 addresses for each .ir name server, but the .ir zone currently does not. c.nic.ir in the root has glue for a name server in NL that is still responding authoritatively on both A and AAAA addresses, but it is surely out of sync.

    Oddly, the ir zone has an OVH IP4 for c.nic.ir which is not responding.

    #AS57497 (faraso .org), a hosting provider, is one of the few IR associated nets currently visible in routing tables. At least some of these prefixes appear to be originating from IR.

    I have to assume he or whoever is responsible for the site has abandoned it, but someone is paying to keep the name and site running. Even more gambling links have since been injected throughout various pages.

    I never received a reply to my email about it.
