For maximum SEO benefit. Should I go for 2 C Class IP's each in different blocks or in same block? Only experienced and professional advice needed.
IP Classes doesn't matter as far as I know.. What matters in regards of SEO is the geo location of the IP.
So I should choose Germany or USA? If I use 2 C Class IP's in same C Class block for 1 website then will there be any problem?
Shouldn't be any problem. If your site is targeted for German users, then go with a German IP. If your target audiences are US or International, go with a US IP.
