# Ip2asn
> IP address to autonomous system number (ASN)
This library uses the free IP-to-ASN service provided by [iptoasn.com](https://iptoasn.com/)
## Installation
$ gem install ip2asn
## Usage
```ruby
require 'ip2asn'
IP2ASN.check("8.8.8.8")
# => {
# "announced"=>true,
# "as_country_code"=>"US",
# "as_description"=>"GOOGLE - Google LLC",
# "as_number"=>15169,
# "first_ip"=>"8.8.8.0",
# "ip"=>"8.8.8.8",
# "last_ip"=>"8.8.8.255"
# }
```
Get raw JSON response:
```ruby
raw_json = IP2ASN.check("8.8.8.8" json: true)
```
Download the [IPv4 to ASN map](https://iptoasn.com/data/ip2asn-v4.tsv.gz) and save the file as `ipv4.tsv`:
```ruby
IP2ASN.download_ipv4_to_asn_map(file: "ipv4.tsv")
```
Download the [IPv4 to ASN map](https://iptoasn.com/data/ip2asn-v4-u32.tsv.gz) and save the file as `ipv4_u32.tsv` with IPv4 addresses as 32-bit unsigned integers:
```ruby
IP2ASN.download_ipv4_to_asn_map(file: "ipv4_u32.tsv", u32: true)
```
Read content of the IPv4 map, line by line (this time not saving to a file):
```ruby
IP2ASN.download_ipv4_to_asn_map do |line|
# do something with line from file
puts line
end
```
Download the [IPv6 to ASN map](https://iptoasn.com/data/ip2asn-v6.tsv.gz) and save the file as `ipv6.tsv`:
```ruby
IP2ASN.download_ipv6_to_asn_map(file: "ipv6.tsv")
```
Download the combined [IPv4+IPv6 to ASN map](https://iptoasn.com/data/ip2asn-combined.tsv.gz) and save the file as `ip.tsv`:
```ruby
IP2ASN.download_ip_to_asn_map(file: "ip.tsv")
```
