I2P support forum

Whenever I delete certain entries from my Router address book they come back after a few days, presumably due to re-syncing with the address book subscriptions list. I know I could just export the hosts.txt into private but if a site goes offline it stays in private right? I like having an up-to-date list. Has there ever been any discussion of adding a feature to the I2P DNS to not only delete certain entries but to make such deletion persistent? I'm sure I'm not the only one to have noticed this.

Hallo RedTheOG!
In your scenario, you also obtain addresses from third-party providers. These include some unwanted ones. To remove these permanently, a filter list must be created locally. The addresses to be removed are entered in this list. The unwanted addresses can be removed using simple on-board tools such as "grep (1POSIX)". The whole process can be implemented using a simple shell script: Get and merge all subscriptions, apply filters, discard duplicate entries, sort the list and write the result to the corresponding host.txt. This script replaces the internal router function and can be executed on a time-controlled basis , e.g. with "cron".
