IPv4 Subnet 23.151.232.0/24 blackholed?
by Neel Chauhan 26 Apr '23

26 Apr '23

Hi, I recently got the IPv4 allocation 23.151.232.0/24 from ARIN. I also had my hosting company ReliableSite announce it to the internet. Right now, I can only access networks that peer with ReliableSite via internet exchanges, such as Google, CloudFlare, OVH, Hurricane Electric, et al. It seems the Tier 1 ISPs (e.g. Lumen, Cogent, AT&T, et al.) are blackholing the IPv4 subnet 23.151.232.0/24. Could someone who works at a Tier 1 NOC please check and remove the blackhole if any exists? Normally when ReliableSite announced my prior (then-leased) IPv4 space it gets propagated via BGP almost immediately. This time it's not going through at all. Best, Neel Chauhan

Reverse DNS for eyeballs?
by Forrest Christian (List Account) 25 Apr '23

25 Apr '23

I have a feeling that I might be stepping into a can of worms by asking this, but.. What's the current thinking around reverse DNS on IPs used by typical residential/ small business customers. Way way back in the day I used to generate "filler" reverse dns for all of these ranges .. that is, records like "45.100.51.198.in-addr.arpa IN PTR 198-51-100‐45.dialup.example.com", and then add a forward A record to match. We had a procedure to override this generic domain upon customer request when a static IP was assigned, such as for a mail server. As time has marched on, and other people were responsible for the reverse dns zones, cruft from old customers no longer with us has accumulated in the reverse DNS override file and I recently discovered that many newer ranges are either nonexistent or not updated. As I'm in the process of cleaning up several other related messes, I'm feeling I should clean this one up too. I've kinda felt for a while now that reverse dns isn't really needed for the customer IPs but before I dump the whole thing overboard and switch to returning NXDOMAIN unless the customer really needs a reverse dns record I figured I'd ask what the current thinking is for these among the internet community. I'm not talking about reverse dns for infrastructure/router IPs here, as I still feel those need to be kept up to date. This is just for the individual end user IPs.

Other people on their street do have Kinetic, and I believe Windstream laid cable from the street to their house, but they are being told there are no facilities to connect them to an OLT or some other type of termination device.

SoCal T-Mobile IPv4 sites inaccessible
by Samuel Jackson 24 Apr '23

24 Apr '23

I posted this on the outages mailing-list too, and I am hoping to get more eyeballs on this while also checking in to see if this is isolated to just us. On T-Mobile, we do not seem to be able to get to ipv4 sites. ipv4.google.com does not load, ipv6.google.com does. Even www.t-mobile.com does not seem to be working. I Tried this with LTE (phone) and their home-internet service. Anyone else seeing this? Thanks in advance.

Windstream/Kinetic OSP assistance/clie sought
by Justin Streiner 23 Apr '23

23 Apr '23

Some of my family recently moved to an area of North Carolina where high-speed residential Internet connectivity options seem to be very limited. Outside of the options below, the only thing they're able to get is satellite Internet service, and the performance has been very poor They moved into an area where the neighbors have Kinetic (Windstream's Internet service) but my relatives have been told that there are no facilities available for them. This is new construction, so perhaps it's possible that their address hasn't been added into whatever systems Windstream/Kinetic use for service pre-qualification? Is there anyone I can talk to at Winstream to find out if it is indeed possible to get service at their address, or if there is way I can get past the gatekeepers? Any guidance from someone in the know at Windstream would be greatly appreciated. Thank you jms

Looking to work through GeoIP issue with Square
by Frank Bulk 21 Apr '23

21 Apr '23

My google-fu is failing me - I'm looking to find out which GeoIP service Square uses, or a path to work through a GeoIP issue with them. A client of ours uses Square and unfortunately one of the blocks (23.247.204.0/22) we received at ARIN was at one time associated with France. As you can imagine, they've geo-fenced some of their financial services. The GeoIP issue was fixed on MaxMind many months ago, and another client worked through this issue with AWS, but apparently Square uses yet another data source. If someone can help me on or pm me off-list, that would be great. Thanks, Frank AS53347 AS18883
