Sao Tome and Principe (ST) - IPv4 address delegations
Data from RIR websites as of: Mon Jan 12 2026
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".
