My established practice is to manually approve all new Forum members. I examine their eMail address and IP address. I have implemented the Forum mod to screen certain foreign countries that only cause us trouble. Today, something new appeared and I don't know what to make of it. An otherwise fine member request has an odd IP address. 10.10.1.141 That is a "reserved" address for things like private nets and multicast. How should I interpret this? I don't know how this visitor has this IP address. Is it safe to permit her to join? I welcome any feedback.
An IP address of 10.10 is strictly internal to a private network. If/when someone with that IP address connects to the wide-area-network (internet, etc), the router will be assigned an WAN IP address and then retransmit the data to the internal computer. It is not possible for such an address to connect legitimately, someone is using an IP spoofing mechanism or proxy. I would NOT allow this person to join my forum.
Reserved IP Address?
