On 22 July 2026, detran.sp.gov.br dropped all three of its existing nameservers and added five replacements in a single recorded move.[^1]

The outgoing entries were ns1.a0.impervasecuredns.net, ns1.a1.impervasecuredns.net and ns1.a2.impervasecuredns.net. The five incoming entries are dns1e.sp.gov.br, dns2e.sp.gov.br, dns3e.sp.gov.br, dns4e.sp.gov.br and dns5e.sp.gov.br - all carrying the sp.gov.br suffix.

The read here is that this is a complete delegation swap, not a partial adjustment: nothing from the prior configuration was carried forward. The move from three nameservers to five also changes the redundancy count, though the facts do not say whether that was deliberate.

What to watch is whether the sp.gov.br nameservers appear across other state-level domains in subsequent recordings - that would suggest a coordinated shift rather than a single-domain decision.
