Public Suffix List (PSL) Pull Request (PR) Template

Each PSL PR needs to have a description, rationale, indication of DNS validation and syntax checking, as well as a number of acknowledgements from the submitter. This template must be included with each PR, and the submitting party MUST provide responses to all of the elements in order to be considered.

Checklist of required steps

[X] Description of Organization
[X] Robust Reason for PSL Inclusion
[X] DNS verification via dig
[X] Run Syntax Checker (make test)
[X] Each domain listed in the PRIVATE section has and shall maintain at least two years remaining on registration, and we shall keep the _PSL txt record in place in the respective zone(s) in the affected section

Submitter affirms the following:

[X] We are listing any third-party limits that we seek to work around in our rationale such as those between IOS 14.5+ and Facebook (see Issue #1245 as a well-documented example)
- Letsencrypt
[X] This request was not submitted with the objective of working around other third-party limits
[X] The submitter acknowledges that it is their responsibility to maintain the domains within their section. This includes removing names which are no longer used, retaining the _psl DNS entry, responding to e-mails to the supplied address. Failure to maintain entries may result in removal of individual entries or the entire section.
[X] The Guidelines were carefully read and understood, and this request conforms
[X] The submission follows the guidelines on formatting and sorting

For Private section requests that are submitting entries for domains that match their organization website's primary domain, please understand that this can have impacts that may not match the desired outcome and take a long time to rollback, if at all.

To ensure that requested changes are entirely intentional, make sure that you read the affectation and propagation expectations, that you understand them, and confirm this understanding.

PR Rollbacks have lower priority, and the volunteers are unable to control when or if browsers or other parties using the PSL will refresh or update.

[X] Yes, I understand. I could break my organization's website cookies etc. and the rollback timing, etc is acceptable. Proceed.

Description of Organization

MikroTik is a networking equipment manufacturer that develops various features for their devices, including a DDNS feature that allows to receive a unique (based on device's serial number) DDNS that resolves to the device's WAN IP address. Submitting this as an employee of MikroTik's server administration team.

Organization Website: https://mikrotik.com

Reason for PSL Inclusion

MikroTik routers provide a feature that allows the user to request a DDNS (https://help.mikrotik.com/docs/display/ROS/Cloud#Cloud-DDNS) for their device so they can access their device remotely even when they have a dynamic IP address. There is also a feature that allows to request a valid SSL certificate from Let's Encrypt using a certbot, which can be used to access the device's management interface using HTTPS or even run containers with embedded web servers.

We would like to be added to the PSL in order to increase the (cookie) security for our device users since the right part of the domain (sn.mynetname.net) can be found on various devices around the world that are not related to each other. The domain is owned by us for many years and is valid for 3 more years and we intend to hold the domain for many more years.

We are aware that Let's Encrypt does have rate limits, but we already have requested Let's Encrypt to increase the said limits.

Number of users this request is being made to serve: Currently we serve over 2 million users (DDNS) daily, though the number changes on various factors and the total amount of DDNS entries is significantly larger.

DNS Verification via dig

dig +short TXT _psl.sn.mynetname.net
