I ended up reinstalling. There were two nameservers in resolv.conf that I did not recognize and do not know where they came from. Now I am able to surf after a fresh install and only doing the critical updates, not all which included kernel update.
I need to ask though, in future if I have to, how does one disable ipv6 in kernel? I tried adding line,
ipv6.disable=1 but my Corporate 2 still showed this when I tested it:
lsmod | grep ip
ip6table_filter 1167 0
ip6_tables 9946 1 ip6table_filter
ipt_MASQUERADE 1307 3
iptable_nat 3064 1
nf_nat 13804 2 ipt_MASQUERADE,iptable_nat
nf_conntrack_ipv4 5195 4 iptable_nat,nf_nat
nf_defrag_ipv4 1065 1 nf_conntrack_ipv4
nf_conntrack 52376 5 ipt_MASQUERADE,iptable_nat,nf_nat,nf_conntrack_ipv4,xt_state
ipt_REJECT 1601 2
iptable_mangle 1211 0
iptable_filter 1206 1
ip_tables 8794 3 iptable_nat,iptable_mangle,iptable_filter
x_tables 13480 10 ip6table_filter,ip6_tables,ipt_MASQUERADE,iptable_nat,xt_state,ipt_REJECT,iptable_mangle,xt_tcpudp,iptable_filter,ip_tables
ipv6 223278 12
whereas, doing same command in Pardus 2011.2 gave no results which meant ipv6 was not being used. I'll have to check this again, as I see the bottom line is the indicator for Corporate 2 (lots of text output, maybe I overlooked that last line which could have shown zero and zero).
