A NOG (Network Operator Group) is a group of network operators that come together to share knowledge, experiences, and best practices related to the operation and maintenance of telecommunications and Internet networks. They usually include internet service providers (ISPs), infrastructure operators, network engineers, and other stakeholders in the sector. NOGs promote collaboration and the exchange of information through conferences, mailing lists, and technical forums, helping to improve the stability, security, and performance of the Internet on a regional and global level. Well-known examples include NANOG (North America), LACNOG (Latin America and the Caribbean), and PTNOG (Portugal).

The assignment of IPs and ASN for Angola is done by the RIR for Africa: AFRINIC

AFRINIC (African Network Information Centre) is the Regional Internet Registry (RIR) responsible for the allocation and management of IP addresses and network resources for Africa; it ensures the fair distribution of IPs, promotes the development of the Internet on the continent, and supports the technical community with training and policies.

DNS.ao is the official page of the entity that oversees the Domains of the AO Zone.

ccTLD stands for Country Code Top Level Domain, and it is the authoritative source that exists in each country for the issuance and management of national addresses on the internet. In Angola, the ccTLD is managed by infosi.gov.ao under the oversight of minttics.gov.ao.

The main difference between IPv4 and IPv6 lies in the format and the amount of addresses that each protocol can provide. Here are the most important differences between the addresses: size, format, exhaustion, and configuration.

IPv4 uses 32-bit addresses (example: 192.168.1.1), while IPv6 uses 128 bits (example: 2001:db8::1), which offers many more addresses. IPv6 also improves security, efficiency, and eliminates the need for NAT. The transition from IPv4 to IPv6 is still ongoing.

APNIC provides statistics on IPv6 usage by country on its website; you can check the statistics for Angola here: https://stats.labs.apnic.net/ipv6/AO
