mirror.selfnet.de new IPv6 address

Hi all, we will soon migrate mirror-1.server.selfnet.de to the new IPv6 address 2a0e:3c0:0:400::52. Can you add this as another address to the allowlist and only remove the current address 2001:7c7:2100:400::52 once we've completed the migration to ensure a smooth transition? Best Regards, Lukas
