IP addresses are used to identify computers and other devices connected to the internet. IP Address Version 6 (IPv6) was designed to replace IPv4. IPv6 addresses are aggregated by prefix. The recommended longest IPv6 prefix length is currently a /48; it can be divided into 65,536 IPv6 segments.
The distribution of IPv6 addresses, aggregated by prefix, for countries or territories in the Indian Ocean is as follows:
| /48 | |
| Comoros | 131072 |
| Madagascar | 262147 |
| Mauritius | 1245466 |
| Mayotte | 0 |
| Réunion | 131072 |
| Seychelles | 524290 |
The minimum prefix allocated to an Internet Service Provider (ISP) is a /32, i.e. 65,536 prefixes; hence the numbers in the table seem large.
