IT---my monologue.

Introduction: Into this door deep like the sea, from the red dust is passers-by.

Some people are OSPF and can accept routing tables in various places.

Some people are rip, although with OSPF like Heart, but its heartbeat only 15 jump.

Some people are static routes, love only one person in a lifetime.

I found that I was the default static route. The priority level is the lowest, only 0.0.0.0 as the next hop.

Some people disguise themselves well, VLAN, isolate themselves.

Some people put their own false appearance, Nat conversion, gorgeous high-profile.

Some people refuse to stay, ACL control, close the journey of the mind.

But I have been exposed to the public network forever.

Some people, owning a Mac, can communicate in the intranet.

Some people, have the route table, you can travel in the public network.

Some people, with TCP/IP encapsulation, can pass on the signal of love.

I try to send n multiple syn=1 but are always ruthlessly discarded.

Why VLAN is isolated, you can also use truck to jump to another VLAN. Like marriage, although a red certificate, tied together, but still someone to have an affair.

Why NAT can be a one-to-many conversion. Like Love, in the name of not married, play various roles, can be anyone's bride.

Why TCP/IP three-time handshake and spoofing. Like ambiguous, could have been directly refused, but also to give people hope.

In this network:

Who gave me the Mac-id?

Who gave me the address?

Who gave me the routing table

Who gave me the TCP/IP encapsulation

Give me Mac, why not bind me to a unique IP. But I was overwhelmed by the radio storm.

Give me IP, why not give me DHCP binding, but also to light up the IP conflict, let me go through the network off the shame.

Give me the route, why not give me a clear direction, let me also try to break, to find the fragrance of love, until the 255 TTL value slowly reduced.

Give me TCP/IP, why should be shared in plain text, without ciphertext encryption. Be intercepted in the heart of the password, arbitrary tampering. Finally abandoned the ignore, slowly forgotten.

The net is so false

Mac forgery, ARP attack, address preemption, packet interception, DDoS attack

My Mac, my IP, my route, where my next hop is ....
