Routers primarily modify the "Time to Live" (TTL) field in the IP header as they forward packets. Each time a packet passes through a router, the TTL value is decremented by one to prevent packets from circulating indefinitely. Additionally, routers may also update the "Header Checksum" field to account for changes made to the header, ensuring data integrity. Other fields, like the source and destination IP addresses, remain unchanged during routing.
What else can I help you with?
Which part of an ip packet does the router use to make routing decisions?
the network portion of the destination ip address
Which fields of the IPv4 header change from router to router and why they change?
IP address remains the same. Mac address changes from router to router.
Is a QoS technique that replaces the IP datagram header with a label at the first router a data stream encounters?
MPLS
Which field of ip address is changes from router to router?
The TTL will be reduced by one every time it passes a router. Because this changes the IP header, the checksum also has to be recalculated.The TTL will be reduced by one every time it passes a router.

Are IP address' assigned to the router or the location of the router?
the router is assigned an ip address.
How many bits does the DSCP use in the IP header?
how many bit header Ip v4
What is an IP Router?
A router that is set up to route IP packets.
What is a layer four header?

In the IP Protocol What is the header overhead?
Internet Protocol, or IP, puts a header on every packet that it sounds out. This header is the overhead. All protocols, such as TCP or UDP, will put a header on the packet. The IP header contains information such as source IP address and destination IP address and is used by routers to figure out where to send the packet. ex. you send your friend a 1kb file, but it takes up 1.5kb of bandwidth due to overhead
Is your ip address assigned to your router or to each computer on the network?
Your Router is assigned an IP address that is known as a public IP address then your router assigns out IP addresses that are known as local IP addresses. So the answer is yes and yes!
What is the information contained in the Ip header?
The source and destination IP addresses
Which part of the IP address 172.17.128.47 does the subnet mask 255.255.0.0 tell the router to look for?
172.17
