We don't need a custom `listLocalIPCIDRs()`; Golang now has a builtin:
`net.InterfaceAddrs()`. [0]
This is one of those wonderful commits that removes more lines than it
adds.

When I had introduced ns-hetzner, I forgot to update the records for
ns.sslip.io, which continued to point to the old, deprecated ns-azure.
This commit updates the ns.sslip.io records.
The nameserver on Azure is probably my least-favorite: much slower, much
higher latency. Even though it would've made more geographic sense to
dismantle my GCP nameserver in favor of the Hetzner, I'm using this
opportunity to get rid of the Azure.
And, of course, introduce the Hetzner nameserver with its 20TB of
bandwidth allowance, which I've come to need.
The torrent of traffic I'm receiving has caused my AWS bill to spike
from $9 to $148, all of the increase due to bandwidth charges.
I'm still maintaining ns-aws; the VM still continue to run, and continue
to serve web traffic, and maintain its hostname and IP addresses;
however, it will no longer be in the list of NS records for sslip.io.
There are much less expensive hosting providers. OVH is my current
favorite.
Rather than bloating the code with yet another flag, one that only I
would use, and in only one specific case (ns-aws.sslip.io), it would be
better to simply take ns-aws.sslip.io out of the NS list.
I'm being gouged by bandwidth costs by AWS. Last month's bill was $148,
and all but $9 was about bandwidth.
My bandwidth has been inexplicably climbing since February:
Billing
Month Total GB % increase
2024/2 37.119
2024/3 52.953 42.66%
2024/4 58.745 10.94%
2024/5 69.307 17.98%
2024/6 173.371 150.15%
2024/7 334.064 92.69%
2024/8 539.343 61.45%
2024/9 568.745 5.45%
2024/10 1365.305 140.06%
The new flag will allow me to throttle the AWS bandwidth to ~287 queries
/ second, which, according to my calculations, will max out the free
100 GB bandwidth without dipping into the for-pay bandwidth.

- IPv6: 2001:41d0:602:2313::1
The crux of this is to take the load off ns-aws, which jumped from
$12.66 → $20.63 → $38.51 → $62.30 in the last four months due to
bandwidth charges exceeding 10 TB.
The real fix is to randomize the order in which the nameservers are
returned.
Meant for obtaining wildcard certs from Let's Encrypt using the DNS-01
challenge.
- introduce a variant of `blocklist.txt` to be used for testing
(`blocklist-test.txt`) because the blocklist has grown so large it
clutters the test output
- more rigorous about lowercasing hostnames when matching against
customized records. This needs to be extendend when we parse _any_
arguments
TODOs:
- remove the wildcard DNS servers
- update instructions
- That's where the code is expected to be
- The only reason the code was buried two directories down was because
it was originally a BOSH release
- There hasn't been a BOSH release in over two years; last one was Feb
26, 2022
- Other than a slight adjustment to the relative location of
`blocklist.txt` file in the integration tests, there were no other
changes
