This page gives the list of IPv4 addresses delegated in San Marino (SM) by Regional Internet Registries (RIRs), according to RIRs delegations files: AFRINIC (Africa), APNIC (Asia-Pacific), ARIN (North America), LACNIC (Latin America and the Caribbean) and RIPE NCC (Europe, the Middle East and parts of Central Asia).

Most IPv4 delegations correspond to a single /PrefixLength address range.

Some IPv4 delegations correspond to several consecutive /PrefixLength ranges with the same holder, aggregated together in a single delegation (for example a /23 and the following /24 aggregated in a delegation with 768 addresses). In this case, colum "Prefix" in the following table contains the keyword "Aggreg", and the entry in the text file appears as "FirstAddress-LastAddress".

The status of each delegation is indicated as "Allocated" or "Assigned":

• Allocated delegations are ranges distributed by RIRs to LIRs for the purpose of subsequent distribution to End Users.
• Assigned delegations are ranges distributed by RIRs to LIRs or End Users for their own use and not supposed to be redistributed.

Other possible values for the status are "Available" and "Reserved". Available and reserved ranges are not included in these tables.

Column "Date" gives the date of allocation or assignment for each range in the format "YYYY-MM-DD".

The link on an IPv4 address opens the RIR Whois page corresponding to this IPv4 address in a new window (RIR website).
In the case of AFRINIC RIR, you need to first copy the IPv4 address and then paste it into the Whois page search field.

You can download the list of IPv4 addresses in San Marino (SM) as a text file.
