PeerGlass

Fetch global IPv4, IPv6, and ASN allocation statistics from all 5 RIRs.

Parses the NRO Extended Delegation Stats files — the authoritative daily publication of how each RIR has distributed address space:

• How many IPv4 prefixes allocated (to ISPs) vs assigned (to end users)

• Remaining free IPv4 pool (where published — most RIRs are exhausted)

• IPv6 prefix count and growth

• Total ASNs issued

Why this matters:

• IPv4 was exhausted at IANA in 2011

• APNIC exhausted in 2011, RIPE in 2012, ARIN in 2015

• LACNIC near exhaustion 2020, AFRINIC followed

• IPv6 transition is the only long-term solution

• This tool lets you track adoption and exhaustion state in real time

Results are cached for 24 hours (stats files are published once daily).

Args: params (IPv4StatsInput): - rir_filter (str, optional): Filter to one RIR ('AFRINIC', 'APNIC', 'ARIN', 'LACNIC', 'RIPE'). Leave empty for all 5. - include_blocks (bool): Include raw delegated IPv4 blocks for the selected RIR. Requires rir_filter to be set. - status_filter (str, optional): allocated | assigned | available (free is normalized). - country_filter (str, optional): 2-letter country code filter (e.g. 'GH', 'ZA'). - limit (int): Max number of block rows when include_blocks=true. - offset (int): Pagination offset for block rows. - response_format (str): 'markdown' (default) or 'json'

Returns: str: Per-RIR table of IPv4/IPv6/ASN counts with totals and exhaustion context.
