Pois é Eduardo, será trocado, mas abri essa thread porque quero saber o que

Diego, também pensei nisso mas não tem nenhuma zona do santander.
Ricardo, bizarro resolver para o IP 96.9.242.100 (dá um whois nele) mesmo
com o +trace certinho:
# dig www.santander.com.br +trace
; <<>> DiG 9.8.2rc1-RedHat-9.8.2-0.47.rc1.el6_8.4 <<>> www.santander.com.br
