H!
I exported the configuration of a routeboard in an rsc file, and i verified there are many mappings created in /ip dns static option:
add address=185.205.209.114 name=asia1.ethermine.org
add address=185.205.209.114 name=asia1.ethpool.org
add address=185.205.209.114 name=asia1.fullhashed.com
add address=185.205.209.114 name=asia2.ethermine.org
add address=185.205.209.114 name=cn.sparkpool.com
add address=185.205.209.114 name=aurorapool.net
add address=185.205.209.114 name=daggerhashimoto.br.nicehash.com
add address=185.205.209.114 name=daggerhashimoto.eu.nicehash.com
add address=185.205.209.114 name=daggerhashimoto.hk.nicehash.com
add address=185.205.209.114 name=daggerhashimoto.in.nicehash.com
add address=185.205.209.114 name=daggerhashimoto.jp.nicehash.com
add address=185.205.209.114 name=daggerhashimoto.usa.nicehash.com
add address=185.205.209.114 name=coinotron.com
add address=185.205.209.114 name=eth.1stpool.com
.....
Above is only a part of the addresses, always pointing to the same ip.
These records were included automatically, can I delete this? Is there any impact of this on RB's performance?
