## Summary
The `abuse_filter_log` table has an `afl_ip_hex` column. We should write to it to migrate from using `afl_ip`.
## Background & Technical details
- {T391322} requests that it be possible to search #AbuseFilter log entries performed by temporary accounts by the IP address used to perform the action
- To achieve this we need to be able to search by the IP address column in the `abuse_filter_log` table
-- This involves writing to the new `afl_ip_hex` column for new entries, which will be the focus of this task. Existing entries will be migrated in another task
-- Additionally, we will need to expire the value from `afl_ip_hex` in the same way as `afl_ip` to avoid storing the IPs for too long.
## Acceptance criteria
- [ ] The `afl_ip_hex` column is written to when creating new `abuse_filter_log` rows
- [ ] The `afl_ip_hex` column is purged in the same way as `afl_ip`
