### Description

In our use case we'd like to load the raw IPNS record from our local kubo node with all of its props like `ttl`, `sequence` etc, and the only way to query it from the local node atm is through `ipfs routing get`.

The problem is routing automatically throws if our node is on offline mode. Can you either:

- Suggest a different way of getting the raw IPNS record from our local node
- Add a flag in `routing get` to allow querying the local node in offline mode

Thanks!
