AS10938 AGENCIA ESTADUAL DE TECNOLOGIA DA INFORMACAO - ATI

AS10938 belongs to ATI, the Agência Estadual de Tecnologia da Informação — the state IT agency of Pernambuco, Brazil, based in Recife. Created by state law in 2003 under the Secretariat of Administration, it runs the digital-government platform and shared ICT infrastructure for Pernambuco's state administration.

What it's used for

RIS sees 4 IPv4 prefixes / 28,672 addresses and 2 IPv6 prefixes, against 2 observed neighbours. The IPv4 is 200.238.64.0/18, 200.196.160.0/19, 189.91.208.0/20 and a single /24 more-specific; the IPv6 is a matched pair of /34s carved out of a 2804:1f0a:: allocation. This is a captive government network: state agency offices, public-facing services and the systems ATI hosts on behalf of other parts of the Pernambuco administration. The two-neighbour count confirms it consumes transit rather than selling it.

Notable

The IPv6 deployment is the standout. Plenty of comparable state and municipal networks worldwide announce no IPv6 at all; ATI announces a substantial LACNIC allocation and has split it into two /34s, which is the shape of a network that has actually planned an addressing hierarchy rather than lit a token prefix.

Interesting

The /34 prefix length is itself unusual — an operator carving on a nibble-unfriendly boundary is normally dividing a large allocation between two sites or two purposes. Announcing both halves separately, rather than the covering aggregate, suggests the two halves take different paths or serve different facilities.
