Unable to connect to default bootnode mainnet.ethswarm.org

[PabloCastellano]

Context

Bee 2.7.0 running in docker compose

Summary

After upgrading my node to the latest version, I am finding log lines like:

"time"="2026-03-17 19:01:35.815058" "level"="warning" "logger"="node/kademlia" "msg"="discover to bootnode failed" "bootnode_address"="/dnsaddr/mainnet.ethswarm.org"                                                           

"time"="2026-03-17 19:07:02.241464" "level"="info" "logger"="node/kademlia" "msg"="could not connect to peer" "peer_address"="a15176e18cc670d43705c15eae81724d1f826131de1e0ede76d5008a323b6e7f" "error"="network status unknown: connectOut: protocol: pricing, version:1.0.0: peer not found"

Expected behavior

Default bootnode should work! However the DNS does not even resolve to IP

Actual behavior

Steps to reproduce

Spin up a bee node using default bootnode

Possible solution
