Yes, this is quite common for Internet-over-cable networks. They are often just flat networks with large subnets, ie large broadcast-domains. In LAN environments the broadcast domains are usually designed a lot smaller. Therefor you are not used to seeing that much arp broadcasts. If you look at the ip-addresses in the arp packets, you can map how large the subnets are, that share the broadcast domain with you :-) Cheers, Sake _______________________________________________ Wireshark-users mailing list Wireshark-users@wireshark.org http://www.wireshark.org/mailman/listinfo/wireshark-users
