Show HN: IP Guide – info on IP addresses, Networks, and ASNs

Disclaimer I work for IPinfo.

If you can download the free IPinfo IP to ASN database CSV file. You can run the following command to get the IP ranges of an ASN.

```

grep AS19551 asn.csv | ipinfo range2cidr | cut -f1 -d ','

```

You will need to install the IPinfo CLI to convert the IP range to their CIDR equivalent. I believe the range2cidr command is also available as a standalone binary as well.

After that, you might want to aggregate the IP ranges to bigger ranges. I have used this in the past for this:

I didn't know ipinfo had a cli, good to know, i'll have a Look. Thank you!

I'm currently using ipset, that does aggregation if I remember correctly, but aggregate6 looks good!

The CLI has a bunch of features. I highly recommend checking out the `help` output for the CLI. Personally, I use the `grepip`, `bulk`, and `summarize` commands on a daily basis.

Here's a simpler alternative with IP Guide that doesn't require a CLI:

  curl -sL ip.guide/AS19551 | jq .routes
