RKearneyon How to get a free .arpa domain

As the post calls out, most certificate authorities will not issue certs against .arpa domains. I found this out the hard way when paying for CloudFlare's Advanced Certificates add-on for an .arpa domain I had successfully delegated and registered.

They return failures and exceptions when attempting to generate the certificate for the .arpa domain and then I spent months trying to get a refund (they are very slow to respond) and only caved once I threatened a chargeback for the service not working as advertised.

I’m currently ~6 weeks into a billing issue with CloudFlare. They typically take 5-6 days to respond, ask you for verification to do things, wait another 5-6 days, then they ask you to do it because it turns out they don’t have permission. It’s a mess.

iMessage is not about the color of the bubble. While the color is what's most noticeable to the end user, a non-iMessage chat means:

  2. Photo sharing quality is lowered  
  3. Video sharing quality is abysmal
  4. Messages traverse carrier networks in plain-text
  5. Loss of undo send and delete
  6. Loss of inline replies
  7. Loss of typing indicators and read-receipts (if enabled)

Just to name a few.

RKearneyon Tell HN: It's 2023 and you still can't import .ics files into iOS Calendar app

Remember, Android doesn't only run on mobile phones and managed addresses are just one part of DHCPv6.

You seem to be completely ignoring the other aspects of DHCPv6. Your response comes off as extremely hostile towards others who may have different requirements than yours. Please consider that there could be other use cases beyond what you've been exposed to in the past.

RKearneyon Tell HN: It's 2023 and you still can't import .ics files into iOS Calendar app

> I don't even know what this means.

It means the Android operating system does not implement the DHCPv6 protocol.

> How is it impacting users?

Users of Android devices will be unable to obtain a managed IPv6 address configuration, other configuration, or request an IPv6 prefix (read: prefix, not address) via DHCPv6 Prefix Delegation.

> Are they crying out about it on support forums for the past several years?

For at least 10 years now[0].

RKearneyon Apple Lightning (2020)
