Hmm, well websites typically block access by browsers coming from a range of known "bad IPs" or from IPs that are associated with known malicious software, so it is still a bit odd.
This is likely the problem in the case of
@pentaxuser as well; somewhere in the security chain, someone or some algorithm may have decided to block an entire IP range, throwing out a lot of wheat with the chaff. This can happen if there have been repeated attacks from IP addresses in a certain range; at some point an admin may exasperatedly just block the entire range and be done with it.
Keep in mind that blocks can be enforced automatically; bad/suspect IPs are stored in databases by certain services you can subscribe to and then automatically block these IPs to prevent problems. There's little arbitration on these lists, so there'll be a lot of perfectly valid/benevolent IPs on those lists.
@pentaxuser in case you have a mobile device, you could try accessing the site using the mobile device from a different network than your home internet connection.
Do you have a VPN? Sometimes sights block their servers.
That's true, although in case
@pentaxuser is not using a VPN, he could consider doing so to get out of an IP-based blockage.
Of course it's also possible to try and contact the admin of the site to highlight the problem. They may be compelled to do something about it as this surely cuts their advertising income.
