## IP Ranges
The following IP ranges have been observed:

- `96.7.136.0/24`

- Some of the IPs do not respond, and some take a long time to respond.  
- From basic testing, `96.7.136.0` seems to have the fastest responses.  
- Akamai appears to **advertise** the following IPs:
  - `96.7.136.4`
  - `96.7.137.4`
