Which of the following will make sense for website to track and store in a spreadsheet or some other form of database?

a) domain names
b) TCPs
c)ISPs
d)IP addresses

a) Domain names: It makes sense for a website to track and store domain names in a spreadsheet or database to keep a record of the domains it owns or manages, their expiration dates, renewal statuses, and other relevant information.

d) IP addresses: Tracking and storing IP addresses in a spreadsheet or database can be useful for analyzing website traffic, detecting suspicious activities or threats, identifying geographic locations of visitors, and personalizing user experiences based on their IP addresses.

b) TCPs: It is not clear what "TCPs" refers to in this context. If it is referring to TCP (Transmission Control Protocol) connections, tracking and storing this information in a spreadsheet or database may not be as useful for a website.

c) ISPs: Tracking and storing Internet Service Provider (ISP) information can be valuable for websites to understand their user demographics, target specific regions, optimize content delivery, and tailor marketing strategies. Therefore, tracking and storing ISPs in a spreadsheet or database can be sensible for websites.
