# Migration guide
This repository will be renamed from **asn-ip** to **as-ip-blocks**.
## Migration steps
1. If only consuming plaintext files: just update the download URL, no code changes needed
2. Update repository URLs in your code from `ipverse/asn-ip` to `ipverse/as-ip-blocks`
3. If parsing JSON: handle the `metadata` nested object and `subnets` → `prefixes` rename
## What's changing
### Repository name
- Old: `ipverse/asn-ip`
- New: `ipverse/as-ip-blocks`
### File structure
The file structure remains the same:
```
as/1/aggregated.json
as/1/ipv4-aggregated.txt
as/1/ipv6-aggregated.txt
```
### JSON format
**Old:**
```json
{
"asn": 1,
"handle": "LVLT-1",
"description": "Level 3 Parent LLC",
"subnets": {
"ipv4": [
"177.75.88.0/24",
"177.75.90.0/24"
],
"ipv6": []
}
}
```
**New:**
```json
{
"asn": 1,
"metadata": {
"handle": "LVLT-1",
"description": "Level 3 Parent LLC",
"countryCode": "US",
"country": "United States",
"origin": "authoritative"
},
"prefixes": {
"ipv4": [
"177.75.88.0/24",
"177.75.90.0/24"
],
"ipv6": []
}
}
```
**Changes:**
- `subnets` renamed to `prefixes`
- `handle`, `description` now nested under `metadata` object
- Added `countryCode` field in metadata (ISO 3166-1 alpha-2 code or `null`)
- Added `country` field in metadata (country name in English or `null`)
- Added `origin` field in metadata (values: `authoritative`, `inferred`, `overlaid`, `none`)
### Plaintext format
The plaintext format remains the same with separate IPv4 and IPv6 files:
ipv4-aggregated.txt:
```
# AS1 (LVLT-1)
# Level 3 Parent LLC
#
177.75.88.0/24
177.75.90.0/24
```
ipv6-aggregated.txt:
```
# AS1 (LVLT-1)
# Level 3 Parent LLC
#
2a01:1234::/32
```
