Is it possible to specify a DNS name for GRE tunnels?

Question

Mikrotik

When creating a GRE tunnel interface in Mikrotik, you need to specify Local Address (Although not required) and Remote Address.
Is it possible to write a DNS name in this field?

Answer 1

GRE is a Server-to-Server tunnel, it cannot be dynamic, as it is declared on both sides, respectively, to reduce errors associated with the operation of DNS services, only IP addresses are used, but you can write a script that would check the address of the name, and when made changes to the GRE tunnel.
In general, for such cases, PtP Client-to-Server (PPTP, SSTP, L2TP) are used

Answer 2

No and no need, because static addresses are always used to build a GRE tunnel.
