Is the word redes the same in Brazilian and European Portuguese?

Yes

The word "redes" is identical in spelling and meaning in both Brazilian and Continental Portuguese. It is the plural of rede, which can refer to nets (fishing, mosquito), networks (computer, social media, utility), or hammocks. The only difference is pronunciation:

• In Brazilian Portuguese, the vowels are typically more open or clearly articulated depending on the region, and the final "s" can be pronounced as a soft [s] (as in "sun") or a "sh" [ʃ] (as in "she"), depending on the dialect (e.g., in Rio de Janeiro).
• In Continental Portuguese, the unstressed "e" is often reduced to a near-silent sound (a schwa), and the final "s" is almost always pronounced as a "sh" [ʃ] sound.
