Excessive IP Data Fetching

## Expected Behavior

Fetching IP information should happen only when needed. Specifically it should occur when a new peer is found that has not been seen before. This could also be optimized further so that it's only fetched when a new IP address is seen.

## Current Behavior

Upon restarting the API we are seeing ~45,000 requests for IP data. It seems that for every peer we are re-fetching the IP data unnecessarily.

## Possible Solution

- Fetch IP data for peers we have not seen before
- (Optionally) Fetch iP data for IPs we have not seen before, perhaps by adding a separate db collection for IP data.
