[dns-wg] Changes to Time-to-Live (TTL) values in reverse DNS zones

Dear colleagues, In 2021, we announced a plan to change the time-to-live (TTL) values in the reverse DNS zones that we maintain. You may view the announcement here: https://www.ripe.net/ripe/mail/archives/dns-wg/2021-November/003928.html Many members of the community expressed support for our proposal. Therefore, we are going to make these changes next week on Wednesday 20 April. We will lower the TTL of NS records to 86400 (1 day) and that of DS records to 3600 (1 hour). Note that the TTL of records imported from other Regional Internet Registries (RIRs) will not be affected. Those records will be imported with the TTLs as published by the origin RIR.
